Remembering those who gave

I always think of my uncle who I shared a room with growing up in the 1950's. He was a tail gunner in a B29 .He traveled a lot for work and would never fly.When I was around 10 I asked him why and he told me he saw too many of his friends go down into the drink . I can't even begin to imagine how brave he was sitting in a glass bubble shooting a 50 cal machine gun at some Jap who was trying to blast him out of the sky. He never married,had no real friends,just worked and came home. That is the sacrifice these guys made for us.
