These rules were inspired by Avalon Hill's game "B-17" and John Stanoch's "Blue Sky" rules. Each player commands a "V" of three bombers and also controls two German fighters. The bombers can be either B-17s or B-24s. The fighters either Me110s, Me109s, or Fw190s.

Each hit on a bomber can have from no effect to total destruction of the aircraft. As happened historically, the bombers can take enormous damage, some taking well over 100 hits and surviving!
