Sorry if this question is a little off-topic, but the Off-Topic forum has disappeared. I've been scanning more old family photos and need help identifying some World War II-era aircraft. I scanned the images below from box-camera negatives that are rapidly deteriorating. I'm not certain, but I have reason to believe they were taken at a U.S. Army Air Force base in Texas where bomber pilots were trained during the war. Perhaps these planes are trainers, but I'm unfamiliar with the types. Can anyone please identify them?
