A pilot's aircraft is hijacked by terrorists.
Did You Know?
The film's title alludes to squawk code 7500. In the event of a hijacking, the pilot inputs ("squawks") the code into the transponder, an onboard electronic device used to identify the aircraft on air traffic control (ATC) radar monitoring systems. Squawk code 7500 silently alerts ATC of the situation without the hijacker's knowledge. See more
