Howard also had a cutaway at the '72 Nats in Glenview that I clearly recall (most of it, anyway). The Nemesis 2 was stuck doing inside loops and continued to do so at about a 30 degree angle of ascent away from the flying circle until is was a LOOOONG ways away (a tiny speck) and couple hundred feet (or so) in altitude. It then ran out of fuel, and lazily spiraled to the ground. Somebody on a moped (I think I recall?) retrieved it and brought back the wayward combat plane and gave it to Howard, who then posed proudly with his prodigal Nemesis as his adoring fans snapped pictures. The airplane was a little worse for the wear, having some silk covering torn back on one side that would have been easily repaired.
So, perhaps we CAN find a way to blame Howard for all of this?
