This is Matt Younkin doing aerobatics in a 1943 Beech 18, known to the US Army as the AT-7C. During the war, this aircraft was used as a navigation trainer before passing into private hands. More pics to come. It’s going to take me a while to wade through the 1,500 or so that I took and edit the keepers. I think this one’s a keeper.
