X-Wing Easter Egg - Famous Pilot

It has been a while since I played this game, so I don't remember if you create a pilot within the game, or by making a copy of the Topace5 pilot in File Manager and renaming it. I believe it is the latter.
If you create cloned pilots with numerous names, once you are in the game assigning pilots to your fighter groups various faces (some alien) come up.
The Egg is that if you create a pilot named Yeager, the face seen in the game is that of legendary test pilot and Right Stuff possessor, Chuck Yeager.
