Factual error: There is a close-up of a parachutist's boot as he leaves the aircraft. It is a DMS boot. DMS boots were not issued to the army until much, much later. Late sixties, early seventies as I recall.
Revealing mistake: As Sean Connery steps on board the aircraft, at the top left two aircraft are shown flying overhead, but backwards, presumably stock footage run that way for some reason. (00:39:20)
Suggested correction: The fighters are not flying backwards. Simple as that.
Suggested correction: Expecting 1970's paratroopers to wear 1940's boots is hardly an error. There were no 1944 issued boots for the 200 odd para's to wear! Anyway I used to jump with non issued Corcoran jump boots instead of issued Army boots.

An attempt to correct this was already made. In this type of film, it is a very valid mistake, just as if cars from the 60's or 70's were seen in the film. Even if the viewer doesn't expect characters not to wear era appropriate attire, it still a mistake, which is the point of this whole website.
