Day 4: 10:00 P.M.-11:00 P.M. - S4-E16
Corrected entry: Airforce One was chased and shot down by an F-117A stealth bomber by a disgruntled marine aiding the terrorists. The F-117 is not a stealth fighter. It carries Air-ground missiles and air-ground bombs but it cannot be modified to carry air-air missiles due to its down looking radar (which is probably why no missile type was named specifically).
Correction: I am a pilot in the Air Force and I know for a fact that an F-117A is a stealth fighter, and is absolutely capable of launching air-to-air missiles.
