00:00The National Transportation Safety Board says the fatal crash of an Air Canada jet at New York's
00:04LaGuardia Airport earlier this week likely involved multiple failures. In a press conference
00:10Tuesday, the NTSB detailed the final three minutes before the crash. Everything seemed normal until
00:16just over a minute before the incident. An airport vehicle contacts the tower but is
00:21kind of stepped on by other radio traffic. 23 seconds later, the tower asks which vehicle
00:27requested clearance to cross a runway. 12 seconds later, truck one, the one involved in the crash,
00:33contacts the tower again. It gets cleared to cross. Now this is 20 seconds before impact.
00:39The truck reads back the clearance they were just granted and that's common practice.
00:43Now we're 17 seconds before the collision. Eight seconds later, the tower tells truck one to stop
00:49just as a sound consistent with a plane landing is heard over the radio. Four seconds later,
00:55the tower tells the truck to stop again. Four seconds after that, the fatal crash occurs.
01:00Now, like I said, the NTSB believes it was likely a bunch of different things that went wrong kind
01:05of simultaneously. Chairwoman Jennifer Homendy shared at least one of the problems. The truck that crossed,
01:12that crossed the runway there, didn't have a transponder, which is what allows air traffic
01:17control to see its precise location on the airfield. When asked if the truck should have had one,
01:23how many said this? That's something we'll determine as part of our investigation. I will
01:27tell you that as not having a recommendation. Yeah, they should. Even though we don't have a
01:33recommendation, air traffic controllers should know what's in, you know, before them, whether it's on
01:39airport surface or in the airspace, they should have that information to ensure safety. Now that's
01:44not an NTSB recommendation. So I want to be clear, but it could be.
