Corrected entry: In many scenes of the interior of the original aeroplane, in Flight of the Phoenix, up to three fire extinguishers can be seen. These are red fire extinguishers and would therefore have contained water. One of the main issues in the film is the lack of water; it seems strange that no one takes advantage of this source of water.
Corrected entry: When attempting to start the engine of the rebuilt plane, the propeller simply rolls to a lazy stop instead of a "lumpy" kind of stop then rocking back and forth a little like in a real aeroplance engine.
Corrected entry: In the scene where the Phoenix is finally taking off you can see wheels mounted in the skis, even though it was established earlier in the film that the only way to build take-off and landing gear for the plane was with sand skis.
Corrected entry: 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.
