A man with a briefcase entered the cockpit of Western Flight 701. The man tells the pilots there are 2 bombs on the plane and a grenade in his suitcase. For 20 hours - a couple terrorized the entire flight in hopes of having their demands met. They wanted $3 million dollars in cash, 5 parachutes, a woman on trial for murder to be handed over to them, and a flight to Vietnam. And for decades they got away with it - because the sky is the limit Source: "The Skies Belong To Us" - by Brendan I. Koerner (honestly, one of my favorite books ever and this episode does not even come close to how thorough, entertaining, and gripping this book was. 10/10 must read)
