00:00Hi there, I'm Tucker. Me and my human travel all the time, and together we've gathered a lot of pet
00:06plane traveling tips we'd like to share with you today.
00:09Now, I may be a dog, but my human always makes sure I have my own suitcase.
00:14It includes my health certificates and medical records and all my human's contact information.
00:20These are all in a pocket that's easily reachable, so we can provide them to the airport personnel if necessary.
00:26We always make sure I have all my food and bowls, as well as all my grooming tools and products.
00:33That includes my brush, some pet wipes, my leash, and bags for when I need to use the doggy restroom.
00:39I once lost my collar on a hike, so we never forget to bring a spare collar with my ID
00:45tag.
00:46Now, if we're going on a longer journey, I always bring my favorite toy and a blanket.
00:51It keeps me calm and comforted in each new location we visit.
00:55My human always makes sure to bring a list of dog-friendly restaurants and attractions.
01:01I always like to know my itinerary before I travel, otherwise I get a bit fussy.
01:07Airlines only let a limited number of pets on each flight, so my human always books me early.
01:13That's because some airlines have requirements that can take months to prepare.
01:17Now, I'm a Labrador, so there are no restrictions for me to fly on most airlines.
01:23But some cat and dog breeds aren't allowed to board planes because they're a bit more sensitive.
01:29Some short-nosed breeds, like the Boston Terriers, Boxers, and Pit Bulls,
01:33can't travel in the cargo hold because they may be prone to respiratory problems.
01:38But they may be able to travel with you in the cabin if they fit the size requirements.
01:43I'll most likely be separated from my human on board the plane.
01:47So, he needed to get me a special crate approved by most airlines.
01:51It's large enough for me to stand, sit, and turn around.
01:55It's also lined with an absorbent bedding, just in case I get too nervous on board.
02:00Now, if your pup hasn't traveled in a crate before,
02:04do buy it in advance and let it get used to the new environment.
02:07With proper training, we'll actually enjoy staying in the kennel.
02:11We'll see it as a safe, comfortable place we actually like to hang out in.
02:16The easiest way is to just feed the dog in the kennel a few weeks in advance,
02:20leading up to the flight day.
02:22Adding a comfortable bed in there and the dog's favorite toy
02:26is also something us pets like a lot.
02:29If our flight has a layover,
02:31we always pack a bit of dry food for me to enjoy
02:34in case I need a snack between the trips.
02:36The airline personnel will be nice enough to help me with it.
02:40Now, me and my human came up with this neat trick in case I get thirsty too.
02:44We freeze my filled water dish the night before.
02:47This way, it doesn't spill during loading
02:50and will melt by the time I'm thirsty.
02:52My human always makes sure that my crate door is closed but not locked
02:56so the airline people can open it in case there's an emergency.
03:01My crate is filled with ways to identify me too.
03:04It has the words live animal written all over
03:07and my owner's name, cell phone, and destination phone number are also provided.
03:12We've even stuck a nice photo of me on the crate just in case I get lost.
03:17They'll know where to return me and how to contact my human.
03:21Oh, did I mention I'm half cyborg?
03:24Don't want to brag or anything,
03:26but my human did provide me with a microchip
03:29that may come in handy in case I get lost.
03:32It has all my information, like health records and ways to contact my human.
03:37Most airports and vet offices have special tools to scan it.
03:41Now, I really don't like this tip,
03:43but I get it.
03:44It's for our safety, blah, blah, blah.
03:46You shouldn't fill the pet's crate with a lot of toys.
03:50If the crate is too full,
03:51it makes it difficult for us to move around and adjust our position.
03:55Now, flying with a cat or a dog may make you eligible for early boarding.
04:00Ask beforehand if that's a possibility.
04:03Getting us settled before the flight can take some time,
04:06and those extra minutes can help both of us remain calm.
04:09Now, my human makes sure to tell every airline employee he sees on the ground and in the air
04:15that he's traveling with me.
04:17This way, they'll know if I need any special attention.
04:21I remember one time our plane got delayed,
04:24so my human made sure the airline personnel checked on me whenever they could.
04:29Really don't like this one either,
04:31but it's best to feed us pets a bit less before the flight.
04:35Some of us get airsick too,
04:37so keeping our tummy empty for a bit might help.
04:40Just skip the last meal you would normally feed us before beginning your journey.
04:45You know how it's best to go to the bathroom before boarding a plane?
04:48We need it too.
04:50So go look for a pet relief area in your local airport.
04:54Most of them should have one.
04:55Some smaller dogs, generally under 20 pounds,
04:58may be able to travel in the cabin with you.
05:01That's only if they're well-behaved and properly groomed.
05:04Always remember that most airlines will be able to refuse to board your pet at any time
05:10if the animal doesn't comply with the regulations.
05:13Also, keep in mind that the dog carrier you bring into the cabin
05:16will likely count as a piece of carry-on luggage.
05:20All throughout the flight,
05:21your pet needs to be safely placed under the seat in front of you.
05:25There will be no potty or cuddle breaks.
05:27Us dogs need to be in the crate at all times.
05:31Now, not all people like pets.
05:33I can't imagine why.
05:34And some may also be allergic.
05:36So it's best to keep us as contained as possible.
05:40Do talk to us to calm us down if we become nervous.
05:43We always like to hear your voice.
05:45Us pets really don't like to be away from our humans for long,
05:49especially in a new location.
05:51So please book a non-stop direct flight if you can.
05:55Fewer stops mean less stress for us, too.
05:58You can also pick a weekday flight.
06:00Airports tend to be a lot less noisy on weekdays.
06:03If we can't go with you in the cabin
06:05and have to travel in the cargo hold,
06:08it's best to fly in the morning or evening during the summer
06:11and midday during the winter
06:12to avoid extremely hot or cold temperatures.
06:16Okay, I'm on the plane now,
06:18all safe in my kennel,
06:19with my water, toy, and some treats.
06:21But where am I exactly?
06:23Me and my human look that up, too.
06:26I'm in a place called the forward cargo hold of the plane.
06:30It's located beneath the cabin
06:31where the human passengers sit.
06:33The reason why we travel in this specific area of the plane
06:36is because it's temperature-controlled and pressurized.
06:40We also don't travel with standard baggage
06:42because of the potential hazard risk.
06:45Now, in case you're wondering
06:46how much all of this is going to cost,
06:48the short answer is it depends on your pet.
06:51Prices vary depending on the transportation manner,
06:54the airline, and also the breed of the animal.
06:57You can expect to pay anywhere between $75 to $125
07:01each way for pets traveling inside the cabin.
07:05Some $200 are needed for pets that are in cargo.
07:08Very large dogs, however, can cost up to $2,000
07:12since they do take up a lot of space.
07:15Once you get to your destination,
07:17go straight to the airline's specified cargo location.
07:20Us dogs are available about two hours after the flight's arrival,
07:24and we must be picked up within four hours.
07:27Otherwise, we'll be taken to a vet or boarding facility.
07:31So, please hurry!
07:32Take us for a walk right away.
07:34We need a bit of a stretch, too.
07:36That pet relief area in the airport
07:38will also be a nice place to take us to.
07:41Oh, and don't forget the mandatory head pats and belly rubs.
07:45Ha ha ha ha!
07:46Yeah, right there!
07:48Welcome aboard our flight from London to Miami.
07:51It will take us four hours and thirty minutes.
07:54The weather in Miami is...
07:55Wait, did the pilot just say four hours and a half?
07:58It sounds like a dream,
07:59but it will most likely become our reality
08:02in less than ten years from now.
08:05Boom Supersonic, an aircraft manufacturer,
08:07is working on a passenger supersonic jet called the Overture
08:11that will be able to carry 65 to 80 people
08:14at twice the speed of current commercial aircraft.
08:17One of the major American airlines
08:19is interested in buying around 40 planes.
08:23The plane that's going to cost $200 million
08:26has recently passed the wind tunnel tests.
08:29If all goes well,
08:30the first finished Overture prototype
08:32will roll off the line in 2025
08:34and will travel at nearly twice the speed of sound.
08:38The plane will be able to show its top speed over the sea,
08:41so it should be ideal for transatlantic flights.
08:44And then,
08:45traveling from, say, New York to Paris
08:47should take no longer than four hours.
08:50But first,
08:51it will have to get all the official permissions to do it.
08:55Some people are skeptical
08:57about the whole passenger superjet concept
08:59as they remember the story of the Concorde.
09:02That high-end plane delivered people
09:04from London to New York in about three hours
09:06and serviced other transatlantic connections.
09:09The tickets cost a whopping $10,000 per seat
09:13and passengers got access to a super-exclusive lounge
09:16with lobster and Angus beef for lunch.
09:19The Concorde went on its final commercial flight in 2003.
09:23It was a huge fuel guzzler.
09:25Plus,
09:26there are many complaints from people living near airports
09:28about the noise it produced.
09:31The Overture is supposed to be more fuel-efficient,
09:34lighter,
09:34and have better software to make it more aerodynamic.
09:38The noise might still be a problem, though,
09:40because supersonic aircraft
09:41need aerodynamic engines,
09:43which are pretty loud.
09:45That will definitely change in the future,
09:47as planes have gone a long way
09:49since their first flight in 1903.
09:52Back then,
09:53the Wright brothers started the Aerial Age
09:55with a 12-second flight
09:57traveling 120 feet in North Carolina.
10:00The top speed at that time
10:01was around 30 miles per hour,
10:03but it still seemed pretty impressive.
10:06The world's first passenger airline service
10:09took off just 11 years later.
10:11The flight from St. Petersburg, Florida,
10:14to Tampa, Florida,
10:15lasted 23 minutes.
10:16Covering the distance by car around the bay
10:19took about 20 hours,
10:20so that was a great time saver.
10:22The tickets cost $5
10:24and were sold out 16 weeks in advance,
10:26but the airline went out of business
10:28in four months.
10:30The new age in aviation
10:32began in the 1950s
10:34when they introduced
10:35the turbofan engine.
10:37It became possible
10:38as they started using
10:39temperature-resistant materials
10:41and complex air-cooling systems.
10:44Planes also became lighter
10:45as they were made
10:46of composite materials.
10:48The wings have also improved
10:50over the years.
10:51The airfoil,
10:52that's the part thanks to which
10:53the air travels faster
10:55above the wing than below it,
10:56became a real game-changer.
10:58Thanks to it,
10:59the planes keep a low speed
11:01during takeoff,
11:02which means they move smoothly
11:03and burn less fuel.
11:05The fastest plane in the world so far
11:08is North American X-15.
11:10It was rocket-powered
11:12and made of aluminum and titanium.
11:14A huge wedge tail
11:15helped it stay stable
11:16at that super speed.
11:18The rocket planes
11:19set the world's altitude record,
11:21reaching an altitude of 67 miles.
11:24Oh, and to make it
11:25even more impressive,
11:26it happened back in 1967.
11:29So, if it was possible
11:31back then already,
11:32why don't we all
11:33just fly rocket planes,
11:34or at least supersonics,
11:36especially on long-distance flights?
11:38In terms of speed,
11:40passenger planes are still
11:42where they were 50 years ago,
11:44mostly because
11:45speeding flights up
11:46would also make them
11:47way more expensive.
11:48Flying faster
11:49means burning more fuel.
11:51Plus, supersonic engines
11:53are expensive to produce
11:54and maintain.
11:56Another reason
11:57is natural forces.
11:58The winds affect
11:59the speed of a plane,
12:00and no technology
12:01can control the wind.
12:03A strong tailwind
12:04can help it move forward
12:05at a higher speed,
12:06and a headwind
12:07can slow the aircraft down.
12:10Planes mostly fly
12:12at altitudes
12:12of up to 7 miles.
12:14Up there,
12:15the air is thinner,
12:16which means
12:17there's less resistance,
12:18and a plane can fly faster
12:19and save some fuel.
12:21Also,
12:22the lower temperatures
12:22make the jet engines
12:24more efficient.
12:25Another perk
12:25of flying through
12:26that part of the atmosphere
12:27is that it's less turbulent,
12:29so flights go smoother.
12:31Private jets
12:32can't fly that high.
12:33They're smaller,
12:34and their engines
12:35aren't strong enough
12:36to reach such an altitude,
12:37so they stick around
12:38to 15,000 feet.
12:41Ever notice
12:42those white trails
12:43that planes leave behind?
12:44Their official name
12:46is contrails,
12:47and they're like
12:48artificial clouds
12:49planes leave behind.
12:50When the plane
12:51reaches its cruising altitude,
12:52temperatures get quite low,
12:54about negative
12:5567 degrees Fahrenheit,
12:56and the water
12:57turns into particles of ice.
12:59The higher the level
13:00of humidity is,
13:01the bigger those trails get,
13:03and you can see them
13:04long after the plane
13:05has disappeared.
13:06So,
13:07thick and long contrails
13:09can be a sign
13:10of an upcoming storm.
13:12Sometimes contrails
13:13can even be colorful.
13:15The droplets of water
13:16that are formed
13:17up in the atmosphere
13:18can freeze
13:18in different sizes.
13:20They all reflect sunlight
13:21at different wavelengths,
13:23causing the effect
13:24of a rainbow.
13:25When all the colors mix,
13:26it appears white,
13:28the most common
13:29contrail color.
13:31Airplanes don't take off
13:33with the wind,
13:33but actually against it.
13:35It's kind of like a kite.
13:37To make it fly,
13:38you launch it
13:38against the wind,
13:39and there it goes.
13:41That's because
13:42there are four forces
13:43of flight.
13:44Lift,
13:45weight,
13:45thrust,
13:46and drag.
13:47The lift is generated
13:49because the speed
13:50of the air
13:50is higher above
13:51the kite
13:52than below it.
13:53The kite is pushed
13:54upwards.
13:55This is the lifting force.
13:57Going through a storm
13:59is one pretty
14:00scary experience,
14:01but is it really
14:02as dangerous
14:03as it seems?
14:04In fact,
14:05the most critical moments
14:06in windy weather
14:07are takeoff
14:07and landing.
14:09Plane manufacturers
14:10test their aircraft
14:11and specify speed limits
14:13at which the pilots
14:14should move
14:15in different weather conditions.
14:16At some airports,
14:18the winds are pretty severe
14:19all year round,
14:20so landing can get
14:21pretty wobbly.
14:22It requires a real pro
14:24of a pilot to land
14:25when the wind
14:26strikes the runway.
14:27Sometimes,
14:28the wind unexpectedly
14:30changes its speed
14:31and direction.
14:32The pilot really has
14:33to know what they're
14:34doing to land
14:34when the wind direction
14:35changes.
14:36Otherwise,
14:37the risk of overshooting
14:38the runway
14:39is pretty real.
14:42Extreme heat
14:42is another weather condition
14:44that can stop
14:44a plane from flying.
14:46Airplanes fly
14:47by generating lift
14:48with their wings.
14:49The air below the wings
14:50takes the plane up.
14:52In extreme heat,
14:53an airplane can't produce
14:54that much lift.
14:56That's because
14:57hot air expands
14:58and becomes way less dense
14:59than cold air.
15:00With less lift,
15:02the plane may find it
15:03really hard to take off
15:04and fly.
15:05Electronics will unlikely
15:07respond well
15:08to extreme heat
15:08or humidity,
15:09and the AC system
15:11may fail.
15:12Smaller jets
15:13can't operate
15:13at a temperature
15:14of over 118 degrees Fahrenheit.
15:17Larger Airbus
15:18and Boeing planes
15:19perform the best
15:21below 126 degrees Fahrenheit.
15:25Those mysterious chimes
15:26you hear during the flight
15:28are a kind of a secret language
15:29the crew uses
15:30to communicate with each other.
15:32The chime you hear
15:33shortly after takeoff
15:34informs the crew
15:35that the landing gear
15:36is getting retracted.
15:38A single chime
15:39during the flight
15:40is a sign
15:40that one of the passengers
15:41needs the assistance
15:42of the crew.
15:43When they're serving meals
15:45and run out of food
15:45and drinks,
15:46they can ask their colleagues
15:47to share
15:48using a high
15:49and low chime combo.
15:51Three low tones
15:52means serious turbulence
15:53is approaching,
15:54so the crew
15:55needs to buckle up.
15:57Have you ever noticed
15:58the flashing light
15:59in the cabin
16:00before takeoff?
16:01You have nothing
16:02to worry about.
16:02It occurs when
16:03the pilot disconnects
16:04a plane from the airport
16:05power supply
16:06and it switches
16:07to the onboard one.
16:08This rapid transition
16:10may cause flashing.
16:12It seems strange
16:13that a commercial jet
16:14doesn't have keys
16:15to turn it on,
16:16but it's a bit more complicated
16:18than just turning a key.
16:19Instead,
16:20there's a series of buttons
16:21and dials on the control board
16:23that starts
16:24the complicated process.
16:26A battery provides
16:27the power to the aircraft
16:28that is charged
16:29through a small
16:30electric generator
16:31within the jet's tail.
16:33Airflow gets in
16:34and moves into
16:35the jet's engines
16:35to keep them cool.
16:37A reserve power
16:38then warms the turbines
16:39by turning them slowly
16:41until they start spinning
16:42at the right rate.
16:43Then,
16:44the engines can be turned on
16:45one at a time.
16:46With up to four engines
16:48on a commercial jet,
16:49this entire process
16:50can take up to 90 minutes.
16:53Planes don't have keys
16:54to lock the doors either,
16:56but when they sit idle,
16:57jets have security guards
16:58constantly monitoring them.
17:00But even if someone
17:02happened to get past them,
17:03it wouldn't be
17:04a quick getaway.
17:05When you enter the plane,
17:07the captain keeps a close eye
17:08on the boarding process.
17:10They are not only in command
17:12of the flight deck,
17:13but also of the passenger's cabin.
17:15To become a commercial pilot,
17:16you gotta have a distance vision
17:18of at least 20-20.
17:20But depending on the airline,
17:22it's sometimes okay
17:23if your perfect vision
17:24is assisted with glasses.
17:26It's time to find
17:27a seat on the plane.
17:28You checked in late
17:29and you've already
17:30had an unpleasant experience
17:32of not getting on your flight
17:33like that in the past.
17:34This is because airlines
17:36purposely overbook their flights
17:38just in case there are
17:39no-shows or cancellations.
17:42So, you didn't get
17:43to choose your seat this time.
17:44You walked past
17:45the front seats in jealousy.
17:47There are seats
17:48that are always taken
17:49much faster
17:49because everyone wants
17:51to leave the plane
17:51as soon as possible
17:53after it lands.
17:54But if you're choosing
17:55safety over early departure,
17:57the back is the place to be.
17:59It's estimated to be
18:0040% safer
18:01in the rear end of the plane.
18:08Maybe you'd prefer
18:09to drive instead of flying?
18:10The chances of something
18:12dangerous happening
18:12to a plane during a flight
18:14are 1 in 11 million.
18:16Compare it to the likelihood
18:17of a car accident,
18:19which is 1 in 5,000.
18:22You've been placed
18:23at the emergency exit.
18:24Excellent!
18:25More legroom!
18:26Over the past 30 years,
18:27legroom has been decreasing
18:29more with every year.
18:30Up to 5 inches
18:32on some airlines.
18:33No, you haven't been
18:34getting taller.
18:35The reason behind this
18:36is the more people
18:37they're able to fit in,
18:38the more money
18:39the airline makes.
18:40Airlines don't build
18:41their own aircraft
18:42and use factory-made planes.
18:44From there,
18:45each airline will determine
18:46its own seating structure.
18:48This is also why
18:49the seats don't line up
18:50with the windows.
18:52But it doesn't matter.
18:53You have the best seat,
18:54although it's always
18:55a bit concerning
18:56when sitting next
18:57to an emergency door.
18:58What if you accidentally
18:59knocked it while asleep
19:00and opened it?
19:02Relax.
19:02It's actually impossible
19:03to open these doors
19:04while flying.
19:05The air pressure inside
19:07pushes against
19:08every square inch
19:09of the cabin.
19:10On the door itself,
19:12this pressure equates
19:13to 1,000 pounds
19:14across every square foot
19:16of the door.
19:16But even if you somehow
19:18developed Hulk-like strength
19:20in your sleep,
19:20you still wouldn't be able
19:22to open it
19:23as there's a series
19:23of electrical
19:24and mechanical devices
19:25that latch it closed.
19:28The extra measures
19:29are important
19:30as the moment
19:30the door opens,
19:31the entire cabin temperature
19:33would quickly drop
19:34and that drastic change
19:35in pressure
19:36would weaken
19:36the plane's structure.
19:39It's time for takeoff
19:40and they've asked you
19:41to turn your phone off.
19:42Should you really?
19:4410% of people
19:45have admitted
19:45that they don't turn theirs off
19:47and don't even set them
19:48to airplane mode.
19:49Cell phones can cause issues,
19:51but they don't disrupt
19:52the electronics
19:53as you might believe.
19:54There is a genuine concern
19:56that while you're flying
19:57in the air,
19:58your phone can receive signals
19:59from multiple towers
20:01on the ground,
20:02providing stronger distractions
20:03for the pilots.
20:04So, let's make their job
20:06a little easier
20:07and turn it off.
20:12The plane has reached
20:1440,000 feet,
20:15your ears have popped
20:16and the seatbelt sign
20:17is turned off.
20:18The flight attendant
20:19walks down the aisle
20:20with their arms held outward.
20:22Within such a thin passage,
20:23they walk this way
20:25as it helps
20:25with their balance.
20:26They try to avoid
20:27disrupting passengers
20:28so they don't use
20:29the headrest of the seats.
20:31And in case
20:32of sudden turbulence,
20:33there are special
20:34grabbing spots
20:35under the overhead
20:35luggage bay.
20:37It's estimated
20:38that half a million people
20:40are flying in the sky
20:41at any given time.
20:42So right now,
20:43you're part of
20:44that special group
20:45involving 0.1%
20:47of the world's population.
20:49You look out the window
20:50and notice the white wings.
20:52Planes are painted
20:53white and other
20:54lighter colors as well
20:55to help reflect
20:56solar radiation.
20:58This avoids damage
20:59from the sun
21:00by reducing the amount
21:01of heat the plane receives.
21:07But further in the distance,
21:09dark clouds approach
21:10and the plane
21:11is heading towards
21:12a thunderstorm.
21:14Since it's made of metal,
21:15it has to be
21:16a big electric conductor,
21:17right?
21:18Thankfully,
21:19jets are fitted
21:20with an aluminum shell
21:21that conducts electricity
21:22very well.
21:24The cabin's interior
21:26is completely shielded
21:27from lightning,
21:28protecting electrical systems
21:29and leaving us
21:30carbon-based mammals
21:31unhurt.
21:32A plane is so perfectly
21:34built for electrical storms
21:35that it's one of the
21:36safest places to be.
21:38There haven't been
21:39any major incidents
21:40from a storm
21:41since the 1960s.
21:43You're thirsty
21:44and you're aware
21:45that you should have
21:46brought your own water.
21:47When aircrafts land
21:48at each location,
21:50they refill their
21:50water supplies.
21:51The water quality
21:52in a plane
21:53is based on where
21:54they collected
21:55the vital liquid.
21:56Many things contribute
21:57to the water quality
21:58of every airport.
22:00Water cabinets,
22:01trucks,
22:01carts,
22:02and hoses
22:02all could be
22:03of different standards.
22:04In 2019,
22:06an airline water study
22:07found that most airlines
22:08weren't providing
22:09clean water,
22:10so the general
22:11recommendation
22:11is to only drink
22:12water from a sealed
22:13bottle and avoid
22:14even tea.
22:15But the food
22:16is perfectly fine.
22:18As you sit back down,
22:20you notice the cabin
22:21is cold.
22:22Super cold,
22:23to be honest.
22:24It's intentionally set
22:25to around 71 degrees
22:26Fahrenheit
22:27for a good reason.
22:28When people become
22:30vulnerable to fainting,
22:31it's due to not
22:31receiving enough oxygen.
22:33And when there's
22:34warm air mixed
22:35with high cabin pressure,
22:36fainting becomes
22:37more common.
22:38So,
22:39while the cold air
22:40is helping those
22:41who need it,
22:41you've been provided
22:42with a blanket
22:43for your comfort.
22:45Warmed up with a blanket,
22:46you notice the dry air
22:48running through your nose
22:49and it dehydrates
22:50your lips and eyes.
22:51But don't worry,
22:52the air is completely
22:53safe and very clean.
22:5540% of the air
22:57is recycled
22:57and goes through
22:58a thorough cleaning system
22:59to remove all dust
23:00and airborne bacteria.
23:02And the other 60%
23:03comes from the outside.
23:05The humidity levels
23:06in the air
23:07get very low
23:08and that's why
23:08you feel
23:09all that discomfort.
23:12It's now dark outside
23:13as the plane
23:14begins its descent
23:15to land
23:16and the lights
23:16are dimmed.
23:17The dimmed lights
23:18aren't for the pilots
23:19or crew
23:20or those at the airport.
23:21They're for you.
23:23If something goes wrong
23:24while landing
23:25when it's dark,
23:26they'll have to start
23:26an emergency procedure.
23:28The dimmed lights
23:29are there
23:29to help your eyes adjust
23:31and help you follow
23:32towards the exit
23:33in the dark
23:34easier.
23:35But luckily,
23:36today,
23:36it won't be necessary
23:37as your journey
23:38has come to an end.
