math riddle
Last weekend, Bowman Field, a small airport I live next to in Louisville, KY, had an Aviation Heritage Festival. Several old historic airplanes were present, and rides were offered on some, including the Ford Trimotor from the 1920's.

One plane that was not here this year, but has been here in previous years, revolutionized air transportation in the 1930s and 1940s. This plane has an association with the number 3523.

What plane is this?
