FMPU Animation Unit

UPDATED! Turner Classic Movies ran the 1943 documentary The First Motion Picture Unit of the Army Air Forces and it did include a section on the animation department. Here is the relevant section. The bit at the end is included because I spotted Frank Thomas in the chow line.


Below are some frame enlargements from it. Can anyone identify any of these people? Click any image to enlarge.
According to Amid Amidi in the comments, the man at right in the above photo is Jules Engel.
According to Amid, the man in the center above facing the camera is Joe Smith.

The man above is possibly Gus Arriola.
A short clip from an animated film about the principles of flight is included in the documentary. This character below represents the drag on an airplane, and his animation smacks of Disney. Perhaps he was done by Frank Thomas or Bernie Wolf.

In a later section of the film, as the men line up for chow, I spotted Frank Thomas in line. He's the fourth from the right. According to Amid, Rudy Larriva is third from right. Are any of the others from the animation section?
