Just to clarify, you've posted that you've completely abandoned the planet and all its military installations right?
Also, it might be more realistic to have your ships jump in from nearby, rather than be in system, considering we've already scanned the system a number of times with specialist scanning ships to reveal everything.
Also, if i was a cunt i'd let you move those ships under the planetary shield. As i've been lead to believe shields only extend out to a planets atmospheric limits or something. If so, your ships have been destroyed because none of the ships you have are equiped with atmospheric capability.
Perhaps someone could clarify the sheild thing for me though?
