behind this c-17. the c-17 is a big plane. it has a loot of turbulence behind it in its wake. they want planes behind it to be five miles away. as they were coming in, the distance between her plane and this plane in front of it had narrowed down considerably. as that distance narrowed down, she got too close. by the time that facility told the tower here at andrews that they were basically handing off control of this. they said it was four miles, when the tower took it over according to "the washington post," the tower said, it's more like three miles. that's how close she was to being behind the other plane as they apreach these runways here. i want to show you some footage -- this is a cargo plane sitting at andrews. and then, of course, we have the other planes such as the one the first lady would be on that are nearby in the same facility.
