Factual error: Unfortunately the whole premise of this film is flawed. You can't cut a twin engined aeroplane up and make a single-engined one out of the pieces. The torque from the second engine prevents the first from flipping the whole aircraft over, as there is no 'axis' through which to rotate. (If one engine fails, the torque from the first can become a big problem.) Without this compensating effect the Phoenix would simply flip upside down and crash as soon as the undercarriage left the ground. Single engined aircraft like the Mustang or the Spitfire have carefully weighted wings to balance the torque of the engine in flight - twin engined aircraft like the Fairchild C82 in this film have no such requirements. The stripped down, rebuilt 'Phoenix' would have no such protection and would roll as soon as it took off.
Continuity mistake: In the scene near the end when the men are done dragging the plane, one of the men unhooks the dragging strap under the left wing. In the next shot, it shows the pilot standing on top of the wing with the strap still attached. When the men climb the ladder to board the plane, the strap is gone.
Factual error: Before the damaged plane is dismantled, in some shots the three propeller blades of the port side engine are a mixture of clockwise and anticlockwise type. (The twist along the length of the blade goes the opposite direction depending on the type).
Continuity mistake: When the Sergeant finds his Captain after the Captain's return, the blisters on his nose are prominent. Later they have disappeared and they come and go throughout several scenes.
