So a jet shooting a missile over Moscow and then turning around to catch up to a missile in DC isn't over the top?
I just thought of it as a fast plane done in the spirit of a movie with lots of fun and creative high tech as opposed to something "dumb". Besides, the space shuttle can cover that distance in about 25 minutes, so I can at least watch a super aircraft in a G.I. Joe movie do something similar without being bothered by it. A car driving up the side of a building with a grappling hook? Or a guy surfing back down to earth on a door? That's a different story.
