Thanks - got those already, I may be looking for what I already know(LOL). I might do better to expand me knowledge of call signs...whew! Another C-17 blows over a low altitude! That always worries the snot outa me cats too. I have alot of flying gas tanks(KC 10/135's), C-17, AWACS/JSTAR, F-15/16's, Sea Stallions, Apaches, Blackhawks and even MIG 29's/Hinds 24's wandering about overhead and always wondered where the Helo's talk as I have not ID'd any of them by call sign yet.
