Early Military Aviation group #2

Wrecked US Army air craft. These were in my Grandpa's scrap book. I have no idea what kind of air craft these are, but they are ruined. My Grandpa was never in the Military, but did work in a factory that made air planes durring WWII, and my mom thinks that in his late teens, early 20's he was a mechanic that worked on air planes. He was always into aviation. Back in the day, when he wasn't talking about planes, or working on them, he was chasing skirts! (see my other post from Grandpa's scrap book)
