The radial engines are definitely something to behold. I am familiar with the "Aluminum Overcast", but I can't remember if I've seen it in person. I've seen several of the ones still flying, and need to buy a ride on one. CAF has the movie "Memphis Belle", and it costs a few hundred dollars a year to be in the CAF, which I wold love to do, but they are in Peachtree City Ga, which is a 1.5 hours from where I live.
