In the Memorial weekend spirit I went up to Double Eagle Airport to look at the WWII vintage Boeing B-17 Bomber. I had always wanted to peek into one. I certainly got a view of what flying into combat in one of these must have been like. Just very thin aluminum between you and the freezing cold and flak and cannon fire from fighters. No protection at all really. My brother Tom paid $400 for a ride in it.
About 4000 of these were shot down in Europe with their ten man crews.
