In American films about expeditions to the moon, the control room is usually packed with white American guys. When Apollo 13 runs into trouble it is an All-American brains-trust that works out how the fix the problem with pipe cleaners and sticky-back plastic. But the Space Program in reality was heavily dependent on overseas talent. Most folk know the part played by Nazi rocket experts in the early days. But not so many are aware of the Canadian and British aviation engineers imported in 1959. That was after the Americans succeeded in persuading the Canadian government of the time to abandon its advanced interceptor plane, the Avro Arrow and the design team lost their jobs. The Americans won twice-over with that one. NASA gained the talent that took it to the Moon and a few years later the Canadians had to buy a very inferior interceptor from the Americans. Hollywood is very bad at acknowledging contributions to American life that did not come from white guys born and bred in the good old USofA. In all those films when the US cavalry charges across the American Southwest to save folk from the Apaches, in real life they could well have been Negros of the 10th or 9th Cavalry. And most of the white cavalry troopers of the time were Italian or German immigrants who could barely speak English. The best Hollywood would do was have the odd tough nut Irish sergeant.
