For the Yak, the old USSR national anthem would be second; the best track I know can be found on Napster : search for "USSR Army Choir Soviet National Anthem". I remember hearing this in "The Hunt for Red october" the first time, but I may be mistaken.
Anyhoo. I also, for some reason, got a kick out of both "The Last Saskatchewan Pirate" done by Captain Tractor when aloft, as well as the USAF Hymn, Blue Yonder.
Jay.
