Through Hell And Back: Plane Expansion Pack 1

From BoardGameGeek:

This aircraft pack is for the game Through Hell and Back. This expansion includes 10 P-47 escorts from the 56th Fighter group from 61st and 62nd squadrons that served in the European theater. There are 10 Enemy Aircraft cards featuring the JU-88, BF-109, and BF-110 from Zerstörergeschwader 26, a Luftwaffe heavy fighter wing that served on the Eastern front. 12 out of the 20 new Aircraft cards have a new optional mechanic for more interesting gameplay. Included is a double-sided Ammunition card that gives new abilities, allowing less reloading. This card can be bought in-game using the crew action card point system. As a bonus, there are two new missions for Operation Thunderclap Bombsight Cards with Dossier Cards. -description from the designer
