With the Memoir '44: New Flight Plan expansion, players can deploy air units such as fighters, fighter-bombers and even bombers to support their troops on the battlefield.
Days of Wonder had released Memoir '44: Air Pack in 2007, but New Flight Plan does something different. From the DoW press release:
"Air supremacy was historically a key factor in WWII, so I'm quite happy that this new expansion features aircraft figures for each of the major nations," says Richard Borg, designer of Memoir '44. "The main goal with the New Flight Plan air rules was to give players the opportunity to use these new rules with any and all official scenarios they choose. This expansion will change most players' Memoir '44 experience forever."
