I bet Evans was so busy watching the other warbirds, he forgot an old helo was here at the airshow.
This is the only one of its type still flying. Its amazing that this type was under design as early as 1943, and became the prototype for tandem engined helo's like the Chinook.
I did see it, but was hoping to see it fly to get a shot of that. But it didn't happen on saturday. It regularly comes to Camarillo though, so I will try to catch it this year, if I am in town.
