Corrected entry: The two helicopters arrive at the ice floe seconds after Gant has taken off in the Firefox. None of the pilots or observers hear or see the receding aircraft or its exhaust trail? None of them see the runway flattened out in the surface of the ice? It would be visible! Are people with such poor eyesight allowed to fly helicopters?
Corrected entry: It's funny how when Clint Eastwood lands the Firefox on the ice to refuel, the American submarine crew immediately attach the U.S designed fuel pump nozzle perfectly onto the Russian designed fuel intake on the Mig that the Americans knew nothing about. How did they even know what type of fuel it takes?
