it is sobering i have some letters my dad sent to his mom when he was trying to enlist at the start of WW2. he broke his knee when he was 22 months old . it left him with his left knee not bending .he wanted to be a pilot but the military would not take him .told his mom that he did not need to walk on the clouds to fly a plane .all he was aloud to serve in was border patrol got sent to montana to guard the border to canada .he never said much about it but he died when i was 10 .but in the letters he wrote i could tell he felt like he was ashamed to not being able to fight .his dad was fugged up with mustard gas in WW1 and in 1952 he killed his self so he was not a burden to his wife any more
