Not only this looks dumb, in real life, that unidentified aircraft won't even get within 100 miles of Air Force One before it's met by a flight of jet fighters and escorted away or shot down.
Also Air Force One has mini-guns in the front of its wings.
Totally impossible, impractical and also useless.
Air Force One is too big for it to be able to maneuver on a dime to get those guns on any target and the target has to be approaching Air Force One directly from the front for those mini-guns to even have a chance to hit them.
It's a heavy 747, not a jet fighter.
