This is a great story about a foiled hijack attempt:
"... the pilot realized the man did not speak French. He then used the plane's public address system to warn the passengers in French of the ploy he was going to try: brake hard upon landing, then speed up abruptly. The idea was to catch the hijacker off balance and have crew members and men sitting in the front rows of the plane jump him, the Spanish official said.
It worked. The man, who was standing in the middle aisle when the pilot carried out his maneuver, fell to the floor, dropping one of his two 7mm pistols. Flight attendants then threw boiling water from a coffee machine in his face and at his chest, and about 10 people jumped on the man and beat him, the Spanish official said."
Reason 101 to pay attention in French class.
