mean that that was caused by either a bomb or a missile. we ve seen airliners break up particularly if they if they descend from very high altitudes. those altitudes, the jet is almost going supersonic. and at the same time, it s almost it s on the verge of an aerodynamic stall. so you fly these aircraft very gingerly at those altitudes. and the reports are the radar data suggests that the plane entered a series of climbs and dives rather rapidly, and then the final plunge. well, what would cause that? because there were these wide fluctuations in altitude, and you used the term aerodynamic stall. what is that? well, that simply means the wing the wind separates from the wings, and the airplane is falling out of the sky. the other problem is going too fast, and the air molecules can t get out of the way. they actually approach the speed of sound, and the shockwaves damage or destroy the structure.
then there s drafting. in drafting, the lea car is hitting the air molecules and getting the drag. by hugging close behind within the first car s slip stream, the second car skips the drag and both cars go faster. now, it s only an extra few miles an hour faster. but even the tiniest advantage counts in a race like this. you might think you always want to be in the lead in this situation. but the extra benefit for the car in back is because it s being pulled along, it has some energy and reserve. the goal is still to cross that finish line first of course. so when it comes time, that second car can use extra energy, speed up and sling slot around the front-runner to victory. it s a technique that s used in all sorts of races. nascar, cycling, speed skating. presidential. oh, yeah. presidential. we saw some superb examples of drafting during this wednesday s republican debate at the ronald reagan library in california. senator marco rubio and ohio governor john kasich like
might be versus ground speed. this is important. the wings don t know anything about the ground. all they know about is air molecules passing over the rig, and that s what gives it lift. that canning very divergent depending on where the wind is coming from was there an updraft, was there a downdraft? there is a number of scenarios that could be at play here which would cause that ground speed to be a little misleading. and why those black boxes are so important. peter, really quickly before i let you guys go the bodies that have been found. you expected investigators are looking at the flight manifest to see exactly where people were sitting on the plane? sure. with 30 victims recovered, you want to know were they sitting in a certain area of the plane? the flight attendant, was she assigned to the rear of the plane, was she in the front of the plane? that might give investigators an initial feel about where the breakup occurred what part of
