With the Old Breed - straight-forward, unvarnished account of Marines fighting on Peleliu and Okinawa.
We Band of Brothers - B25 bomber pilot in the Pacific. There are several books by this name, but this one is by R. E. Peppy Blount. I think these guys were the best pilots, fighter or bomber, and had the most difficult and dangerous missions. Lots of NOE missions. One in which the author came back with the radar mast of a ship he bombed stuck in his wing. Want to know what happens when you strafe someone with 10 50cals? It's in here.
Samurai! - The autobiography of Saburo Sakai - lots of detailed, turn by turn accounts of dog-fighting. Some incidences sound like they could have happened in AH.
Baa Baa Black Sheep - The man, the myth, the Legend: Pappy Boyington! If you haven't read it, you need to.
Terror in the Starboard Seat - I forget the name of the author, but if you can find this book, it's really fascinating, funny and sad. The author was RCAF but he flew as a Mossie navigator for the RAF. I haven't seen many books about Mossie's. This guy flew all kinds of missions. Recon, ground attack, "skulking", chasing down V2s. They tried bombing a bridge once but couldn't hit the target haha. In the skulking missions they would fly around German airfields in France at night, waiting for fighters to return. Then they would get into the landing pattern behind the planes and try to shoot them down. He tells about how terrified he would get when the flak started coming up. So scared that he couldn't speak. His pilot would be asking him questions, but he just couldn't get his mouth to work. Once when they were returning from a recon, the pilot tried to strafe a guy in a cast or something who was laying out on a balcony. I guess he thought it was a German soldier. There was an incident with a flat spin that the barely recovered from. Also they caught someone having carnal knowledge with a sheep.
