Thanks for the comments, folks. I've got two figures that are going in the cockpit. They're from a WWI pilot set by Orion (formerly Dark Dream Studio)
You can see them here:

I got them from the Michigan Toy Company:

I'll be using two of the sitting figures: the guy giving the thumbs up, and the guy with his arm cocked as though resting on something. When they're both in the cockpit, the second guy's arm rests on the the first guy's shoulder. They're both looking left, so I'm going to put one of the officers in their line of sight as though he's givig them final instructions.
There are some ground crew in that set too, so I'm expecting to have a relatively busy scene when I'm all done.
Regards,
