  1. That seems like a near dangerous proximity to the shock wave. I’m not saying it’s lethally close, but it sure appears to be much closer than I’d like to be.

  2. Why didn’t the US honor their agreement with the UK to share information about supersonic flight?

    Are there any other sources about it?

    Why would they do such a thing?

    It surprises me, considering how closely allied the US and the UK were.

    Would this sort of thing be expected to have any sort of consequences, political, or otherwise?


    The British Air Ministry signed an agreement with the United States to exchange all its high-speed research, data and designs and Bell Aircraft company was given access to the drawings and research on the M.52,[28] but the U.S. reneged on the agreement and no data was forthcoming in return.


    DENNIS BANCROFT: The idea was that they had decided that it was a good idea to make a supersonic airplane, and they had heard that we were making one. So, they came over to England with the idea that they would have all the information that we had accumulated, the idea being that a fortnight later, we would go to America and they would give us all the information the Americans had got. But after the Americans had got the information, take the drawings away within a fortnight. When we were trying to arrange the visit, they just said, “Sorry. Secrecy. The Pentagon says you can’t.”
