Airplane High Jack Protocal Signal

The pilot retracts the plane's flaps, which is high jack protocal signal to let law enforcement know that they need to back off. The fbi agents on the ground have no plane high jacking training so they don't know that's the signal. So there's two fbi vehicles positioned around the plane. When o'connor hears the request for fuel, he says there won't be any fuel ater so downs, the pilot, explains that the high jacker has about 12 and a half pounds of plastic explosives. And he advises that everyone does what the highJacker says or they could all die.
