00:00August 9th, 2024 flight 2283 of Brazil's local airline Vopalinhas was seen falling
00:07from the sky in a terrifying manner in different videos.
00:11This plane named AR72500 was a Brazilian passenger aircraft which was going from Cascabel to
00:17Sao Paulo but just a few minutes before landing.
00:21It met with an accident in which 57 passengers and 4 crew members lost their lives.
00:27This was not only the first dangerous crash in Brazil after 2011 but it is also considered
00:32fatal in the aviation history of Brazil.
00:36In the video, it can be seen that the plane is falling from the sky like a cut kite while
00:40doing free fall.
00:43After the release of the video, a wave of fear has spread among the people associated
00:47with the aviation industry because no matter which aircraft it is, it can never come down
00:52in free fall.
00:53The plane always comes down by gliding.
00:57So what was the reason?
00:59Authorities have launched an investigation into this but what happened a few minutes
01:03before the crash that could have caused this accident?
01:06Once again welcome to World Stories video.
01:09Vopalinhas is a local Brazilian airline that covers most domestic destinations.
01:15It has 8 AR72500 aircraft, one of which crashed on August 9th.
01:21The A72 has 2 turboprop engines and the number 72 in its name indicates its seating capacity.
01:29It was built in France and Italy by aircraft manufacturer ATR while Airbus also has a 50%
01:35stake in this company which shares its technology with ATR.
01:40The AR72500 of flight 2283 was 14 years old which will be replaced in 2022.
01:49It was bought by Lenhas from Indonesia's Pata Air Service.
01:53As I mentioned earlier, this airline mostly operates to local destinations.
01:58According to flight data records, it took off from Sao Paulo on August 9th, 2024 at
02:049.06am and its destination was Cascavel, 700 kilometers west.
02:10The trip went perfectly.
02:12It landed safely in Cascavel at 11.01am after 2 hours and 11 minutes.
02:18The flight was already late as per its scheduled time and it had to load passengers from Cascavel
02:23and go back to Sao Paulo.
02:25That is why after unloading, cleaning work was done quickly and exactly 41 minutes later
02:30it took off from Cascavel to go back to Sao Paulo.
02:34There were a total of 57 passengers and 4 crew members including the pilot.
02:3961 Sala Ambit Decompose
02:43The flight captain was 35 year old Danilo Santos.
02:46The first officer and 2 female cab crew were also present.
02:50What happened from takeoff to crash?
02:52What was visible on the radar screen you can also see all this.
02:56At 11.58am local time, flight 2283 took a left turn immediately after taking off from
03:02Cascavel and started maintaining an altitude of 177,000 feet which is also called cruising
03:09altitude at 12.2.
03:11After 23 minutes from takeoff, an altitude of 177,000 feet was maintained.
03:18If you go straight from Cascavel to Sao Paulo, there is a huge mountain range in between
03:23to avoid which all the planes either go over the Pacific Ocean in the east or pass over
03:27the plain land in the west.
03:30Flight 2283 also took a slight left turn to bypass this mountain range.
03:35According to the radar, the first one and a half hours passed in a completely normal
03:40manner in which the altitude of the aircraft was around 177,000 feet and the ground speed
03:46was 460 km per hour.
03:49At 1.7 minutes, flight 2283 took a sharp left turn and changed its direction towards the
03:55city of Campinas from where it was to make an approach and land at Sao Paulo airport.
04:01At 1.2 minutes, when it was present above the population in the south of Campinas, for
04:06the first time its ground speed decreased.
04:09It was earlier moving at a speed of 460 km per hour.
04:14Suddenly that speed became 159 km per hour.
04:18What was the reason for this is not yet known, but in the next minute, 1.2 minutes and 2
04:24seconds, the pilot maintained his ground speed back to 400 km per hour.
04:29By this time, the pilot there was no information of any kind to ATC.
04:34This was the point from where the plane was to be directed towards Sao Paulo airport.
04:39And we can see in the radar that the pilot started to turn the plane to the right.
04:44But only after 13 seconds, at 1.2 and 15 seconds.
04:49When he was turning, suddenly the ground speed decreased and along with it the vertical speed,
04:54that is.
04:55The speed at which the plane goes up or down starts decreasing.
04:59It was seen in the radar that the plane flying at 1,000 feet started coming down at the speed
05:04of 13,000 feet per minute.
05:07It also kept rotating and during this its ground speed, that is, the forward speed,
05:12reduced from 400 to 100 km per minute.
05:16This entire process took only 1 minute and 14 seconds.
05:21That is, in such a short time, the plane fell straight from 177,000 feet to the ground.
05:28During this, the plane fell 180 feet but the plane was coming down at a speed of 100 km
05:34per hour and the pilot probably did not have enough time to alert the ATC about his situation.
05:40The place where the flight's vertical speed started to decrease and the place where it
05:44crashed are only 1.3 km apart.
05:48The real reason behind this sudden fall will be known only after investigation, but according
05:53to the information available so far, information about the formation of ice at an altitude
05:59of 12,000 to 21,000 feet in the area where the crash occurred was given to all the pilots,
06:05which is also called segmental at meteorology information.
06:10If ice starts forming on the wings of the aircraft, it is a matter of great danger because
06:14the ice changes the aerodrome of the aircraft and the air which gives it lift, that lift
06:19is now reduced.
06:21Another problem caused by ice formation is that the wings, doors, ailerons, and elevators
06:26which are the moving parts of the aircraft get stuck between them and they cannot move,
06:30that is, despite the inputs given by the pilot.
06:34The aircraft will not be able to turn right or left.
06:38To avoid this, modern aircrafts often have an automatic heating system which does not
06:42allow ice to form on important parts.
06:45There are some aircrafts on which a special chemical is sprayed before flight which prevents
06:50ice from forming.
06:52ATR 72500 has different types of de-icing systems installed.
06:58Its wings have pneumatic de-icing boots which keep removing ice from the wings.
07:02Similarly, its de-icing systems are installed in the propellers, windshields, and engines
07:08as well.
07:09And despite all this, if there is a forecast of ice, the pilot tries to avoid that altitude
07:14or place where there is a possibility of ice formation.
07:18After the crash, the black box of flight LATU 83 has been recovered and it is expected that
07:23the real reason for this crash will be revealed in the coming months.
07:28But for now, it remains a mystery as to how the plane fell straight down from 177,000
07:33feet.
07:35I hope you all will like and share this video of world stories.
