my father was drafted into the Army Air Corp in 1943. I remember my mother and I traveling to Madison from Minneapolis. i thought he called his base Chanute but I see that was in Illinois. was there a AAC training base in Madison in 1943?

Chanute was a training base in illinois for aircraft maintenance. The air force wasn't born until 1947 however I have heard stories of how the base use encompass matc and covance stretching several stories deep for some type of testing when it was an active duty base dating back to WWII. So unfortunately I do not have any more information but sounds like a good possibility.

Yes, Truax Field is the name of the base in Madison.
