I'm now going to turn to looking at the planes we fly.  To start with, we are looking how often planes are featured in a plane set for a frame.  I found the result a bit surprising.

It took me a bit to figure out why German planes seem to be featured so much more than any other planes.  The best I can come up with is that the Germans used a limited plane set that was flown in all their theaters of operation, while other nationality planes were more specific to a theater of operation.  British planes on the western front.  Early war American planes are hand me downs to Eastern Front, China-Burma-India, and North Africa.  US Naval and Japanese planes for PTO.  So a common plane set used in multiple theaters is going to show up as the most featured planes in FSO.
I still get a chuckle when I see HiTech's RV-8 pop up in our stats.  I've tried hunting for the plane number for it a few times, but haven't found it yet.
