Thanks for helpful clarification in#883,
JS and your observations in #884, PM on the CAA. Many people's summer fun will now be spoiled for nothing whatsoever. But what to do to get these hasty and ill conceived new regs altered? I might try my MP since she is new and seems keen.
(I had a couple of hours in a T7 back in the sixties. Wow. I asked the instructor for guidance on what not to do to break his aircraft. He gave me a look which showed "withering" and "amusing" in equal proportion, and said that there was nothing I could do to damage it - at least, whilst he was still there).
This accident is really sad but the possible consequences are too.
