Easter egg #2!!!
I figured out the 2nd easter egg Friday night, but rain and wind knocked out my house's phone line and they only got it fixed today.
The Trigger™ to the 2nd easter egg:
In the prelude mission, ID and destroy the brilliance container hidden in the asteroids at Nav 2.
That will trigger the 2nd easter egg, which is in the simulator mission 1. After you identify and destroy the contraband containers, along with the mining drones, some Rapier IVs will show up, some of them will be your friends and others will be your enemies. The friendly Rapiers are flown by Zero, Stilletto, Spyder, Dallas (?) and Maestro and all the enemy ships are flown by no other than Lt. Lance Casey.
