|DC-3 Wing Attachment Flange and Bolts|
Watching a good old John Wayne movie, with Marshall Dillon (James Arness) as a fellow pilot flying a C-47 [DC3]
I wonder alot about airplane wing spars. Wondering about the main DC3 wing spar, I didn't find wing spars. Each wing was attached with ~365 1/4' bolts on a flange.
