>> yeah, so that didn't work. that was the supposedly less combustible jet fuel bursting into flames just like it wasn't supposed to. this is the view from inside the cabin of the plane. the test dummies handle the anymore impact of the crash but then the entire cabin justl< fills with flames and it's bye-bye to those poor dummies. when we think about the government crash testing stuff it's the cars with the dummies going head first into the steering column or whatever. it's not always cars. but sometimes it's a full sized commercial airliner with a camera attached to the tail so a government can see what happens when you crash a thing like that into the ground. sometimes it's planes and sometimes it's automobiles but sometimes what the government is crashing on purpose are trains. >> at a railroad testing grounds on the high plains of pueblo colorado, today, the department of transportation
