Deliberate mistake: During the ejection sequence there is a major problem with the parachutes used by the crew. When you see the first parachute open, it is a standard Navy Conical round canopy with 3 colours; Orange, Green and White from the bottom view. A moment later they are flying ram air rectangular parachutes with different colour patterns.
Deliberate mistake: The French NATO rescue team is flying an old, Russian-made Mi-17 helicopter which is not in service in France. It was probably rented in Slovakia where most of the film was shot. The Mi-17 is easily distinguished from the French multi-purpose helicopter Puma: the Mi-17's landing gear is supported by huge rods, its side windows are round, and it has a sleek boom with the tail rotor on the left side. The Puma has smaller gear support, rectangular side windows, and a thicker boom with the tail rotor on the right side.
