Just to tell you how impressive that feat is to me (borading the f*****g executor), I once had a lvl 9 party (4 members, 2 of which level 9 force users) trying to escape (with force tricks and everything) from a Standard Star Destroyer (the Vengeance, or something...the one deployed in Tatooine's high orbit, it is also in the EU). WITH a docked ship waiting for them in one of the bays and the surprise element.

They barely made it (all injured).

And that was a puny 1600 mtr SD....
