Film: Armageddon

Even Ben Affleck pointed out this Armageddon plot hole, which features NASA teaching a bunch of oil drillers how to be astronauts. The problem here is that it takes much longer to learn how to be an astronaut than it does to do the drilling necessary to stop the asteroid, so why not just teach some of NASA's best and brightest how to drill instead?
