I'll take the physicist at his word that he worked it out. I wish they would have mentioned friction - sure the thing was going fast when it left the ground, but the drag from the atmosphere would be ridiculous at that speed and the object not propelled. I'd like to know how much speed it lost by the time it got out of the atmosphere

On the other hand, it will leave most of the atmosphere within a second and has the kinetic energy of the Empire State Building traveling at ~60 miles an hour (40mwh+ if its ~200 pounds). And maybe the nuke's radiation moved some air out of the way? Yeah, that is a problem for a high energy physicist. But intuitively... even if it "exploded," the metal fragments may have still made it to space?
