1952 version worth a look?
Right down at the bottom of the page referenced in post 1 there's a 1952 short film also made by GE telling the same story with fewer errors (though it appears the Whittle engine is being unloaded from a USAF-liveried plane...only 5 years too early for that to be possible. Some nice scenes of early US jets flying, and optimism about nuclear-powered aircraft. Maybe that did happen and we just haven't been told?
