An easter egg ... of sorts

If you choose the Draken livery under the U.S. and look at the cockpit from the external view, it is of the F1M.  Just thought that was kinda neat.

Neat, and a nice sneak peek at the M variant

It's not a easter egg but they forgot to put the right external model, you can see all cockpit variant by changing the arg 70 to have all F1 versions done by Aerges
