I was at the River City Classic giant scale fly in today here in Memphis. Mike Sauls and Blaine Austin were doing a little formation. They both did a snap roll at the same time, then about 2 seconds after that: wwwwhhhhhaaaaammmmmmmppppp!!! Fortunatly both were able to get them down safely. Blaine had a prop stuck all the way through his right wing...and his rudder counterbalance was gone. Mike's firewall broke and the engine was hanging down. I would say they got very lucky. I took some pics...but my stone age camera uses film....so I will scan the pics and get them on here ASAP.
