A man hijacks an aeroplane transporting 8 passengers and valuable cargo. After taking the cargo, the man demands nine parachutes from the flight crew, puts one of them on, and jumps, leaving the other eight behind. Why did he want eight more?
Answer
When he asked for 9 parachutes, the flight crew thought he was going to jump with the 8 hostages (passengers), so they would never risk giving him a faulty parachute.
