Revealing mistake: When the terrorists drop the dead body out the aircraft door, look closely at the aeroplane just beneath the door, you can see the reflection of the mat the stuntman lands on, as well as the spotters around it.
Charles Rane: You wouldn't take advantage of a helpless man.
John Cutter: Never stopped you.
Charles Rane: It's the American way, isn't it, brother?
Trivia: FBI Agent Dwight Henderson is portrayed by Robert Hooks, the father of director Kevin Hooks.
Question: How did the FBI agent know that the two FBI agents on the plane were killed earlier?
Answer: It's been a while since I've watched this movie, but he obviously knows the plane is hijacked. It's a pretty safe assumption that the agents are dead as they're escorting a dangerous, high profile prisoner. Pretty easy to connect the dots. Alternatively, they could've failed to check in, and he assumed the worst.
Answer: When ground crew, first responders, and police are near the plane, you can see paramedics stacking body bags in an ambulance. It's safe to assume the bodies were dumped after Captain Whitehurst was dumped from the plane.
