A man hijacks an aeroplane transporting both passengers (a total of 8 persons) and valuable cargo.
After high jacking the cargo, the man request for nine parachutes, puts one of them on him and then jumps, leaving the other eight behind.
Why did he want nine parachutes if he used only one of them?
If the officials thought he was jumping with a hostage, they would never risk giving him a faulty parachute. 🙂
