RAF & Breaking the Sound Barrier

But Duggy seems to have the answer to the OP’s question. Bee Beamont was not in the RAF at the time.

Bee Beamont 1948

With kind thanks to Twin Otter 23 for the reference, Bee Beamont as an EE Test Pilot went supersonic in 1948 in an F86.

But not a lot more on the subject.

I did it in the mighty Jag, though we were in a dive to do it :eagerness:

RAF Sabre in the fiftys, who god only knows.

But he was not in the RAF then, he was a test pilot for Hawker.

Neville Duke springs to mind, in a Hunter During the 1950’s. The aircraft was at Colerne museum for some years in all red livery.

As opposed to a test pilot, you mean? Would that information, even if recorded, be in the public domain? Presumably pilots of Hunters and Swifts did in a dive. Or perhaps an RAF pilot on exchange in the US….
