You have one labeled P-38 starting as a Corsair taxies by. I thought,
why is the P-38 starting both engines at the same time? I have never
seen a twin do that; must be hell on a battery. Then I noticed that the
Corsair going by has his prop turning at about the same speed as the
P-38. That is odd. His engine must be running, as nobody is towing
him. Then it occurred to me. The camera must have had a very fast
shutter, and what appeared as the twin starting, is also happening to
the Corsair prop; they are both running at idle, and the camera is
nearly stopping the prop, but rapidly enough that it looks as they are
turning slowly.

When Jay first put that video up, there was extensive discussion about the fact
that the Lightning's engines appear to be turning in the same direction, while
it's known that they didn't. I think you've found the reason. It's possible that
the period in which the Lightning's props seem to be stopped is actually a
period in which they were in perfect synch with the camera.

I don't remember if anyone else proposed your theory during that thread. Someone
might have.
