Where's Sam Kydd?

Saw this on Talking Pictures, and I think it must've been cut, because I can't find any trace of Sam Kydd's character, Flight Sergeant Flint, although he gets a credit in both the opening and closing titles, whilst William Greene who plays Lieutenant Mitchell, Kimball's underling, gets nothing. I can only surmise a scene from the flight over to France was chopped.

The end credits are curious because the top four players (Massie, Albert, Gish, Robertson-Justice) are omitted.
