Read Toward the Setting Sun. WWII Doolittle raider plane and what happens after they bomb Japan and ditch over China. Then we may discuss leg pain in survival conditions. Warning: you will feel like a sissy faggot after reading about these gigantic brass balls. Warning 2: I am working from memory here, but the book is an autobiography of one of Doolittle's squadron about the one-way mission and how they lived to tell the tale. I hope I have the right title.
