Yes - I saw the Gnat at Valley and I'm astonished that it stayed in the air. You could se a lot of daylight through the floor and most of the nose had gone although a few avionic boxes were dangling on their cables.....
Then there was the guy who porked up a night toss attack at Wainfleet, but gritted his teeth, rolled wings level and pulled like a bug.ger. Big strong chap, but so was the Bucc. The AR probe bent under the strain, both inboard flaps fell off - he knew about the former but not the latter, so his intended 45-10-10 landing became an inadvertant 0-10-10 landing which made control even more difficult. I think that he pulled over 10g - some reports suggested 14g. But a couple of new flaps, a new probe a thorough check and it flew again, I gather!
