Nigel,
I can recall quite a few years ago my dad and I seeing a guy come into the field (Fry's corner) with a byron P-51 strapped to the roof...unfortunately he had tied the fuse down with the wing on and wind on the wing as he drove caused so much lift without being able to lift the fuse off the car that it snapped. He came to the field anyways....no doubt shamefully....to now sell, instead of fly....one clipped wing byron mustang.
