The Wingleader Deluxe Boxed Set doubled the number of aircraft in the original version of the game and added rules for a campaign game. The Ace of Aces Collector's Guide, by Joseph J. Scoleri III, has this to say:
"The Wingleader Expansion Set was a special addition to games distributed by Chessex Manufacturing. The expansion was added at the time that Chessex acquired Nova's inventory. Dennis Greci estimated that there were approximately 500 of these sets.
A brief review of the Expansion Set shows that it is a "must have" for Wingleader players, if only for the twelve new aircraft cards (which add another 24 aircraft to the game.) Also included are campaign game rules, designed by Alfred Leonardi and Greci, which allow for large scale tournament games. There are also two suggested Speed Bonus rules for dealing with combat between aircraft of varying maximum airspeeds."
