I was lucky.. we had had a warm spell, so the ground was very, very soft. The engine had only one flight on it. It was completely buried (never had one that deep before

) so it had to be totally disassembled and cleaned. No aparent damage, although time will tell. She hasn't been fired up since, though she's due to be run up next weekend in my new H9 Spitfire. She was one very sweet running engine up until that moment.
