Do you know how the GSAP cameras actually worked?


Simple. When the guns were fired the cameras rolled.

I believe I've seen sequences where the film is clearly still running
after the shooting has stopped, so I'm thinking pulling the trigger
started the film rolling, and then it would run a few secs after the
trigger was released.


Possiber. I guess there might have been more inertia in the film transport than
in the firing mechanism of the guns

No, it was a design feature; the camera was intended to overrun for a few seconds
after the trigger was released, allowing for time of flight and high deflection
shots, and subsequent damage assessment. At least some of them had a lever in the
focal path that appeared in one of the upper(?) corners of the film frame, which
showed when the guns were actually firing. Can't remember if it just dropped into
place and stayed there while the trigger was pressed, or if it oscillated in and
out of the frame. You needed to know when the guns were actually firing (or to be
more precise, when the pilot had the trigger depressed) to assess the pilot's
gunnery technique (firing range, lead etc).

Did they ever put gun cameras on bombers?


I certainly recall a few famous shots. The FW190 pilot who after
jetisoning his canopy and pushing himself clear of his aircraft is
seen (from the waist gunners position on a B17 I think) with his arms
flailing in the wind. Don't know if he made it.

Then there is a picture form a German gun camera. Looks like Mk108
30mm chewing up a B17s starboard engine nacel: the undercarriage is
blown clear of. There seems to be a clock in the corner of their
film.






I'd suppose not since there
would be a lot of guns to record, and the wide angle of action would
make for a more complicated camera mounting system.

How about your B-26's with the fixed gun packs up front? Did a GSAP
go with that installation?
