I was USAF back in the mid 60's at a SAC base, and I was always amazed at how many hours that were logged to keeping a keen edge on preparation, and equaly amazed at how few times that tragedy was averted in just this way.
Having served for the short term, I am deeply grateful for the sacrefices that are made by you guys and gals, and just as sad to see this kind of outcome.
My deepest sympathies, and prayers to their families, and to you for the loss of your friends FG
