The recruiting office does not look at any airframe more favorably than another. Getting released from your community will depend on a number of factors including: manning, AFPC quotas, time on station, etc. AFSOC is a tough nut to crack - there have been two guys that have achieved escape velocity in the last 10 years. (2004, 2011). The Mc12 guys can correct me if I'm wrong, but most (all?) line pilots are still TDY to that airframe. You'll have to work your application through your original unit, not directly from the Liberty. Important to note: You will not be considered for an interview unless AFPC agrees to release you to the program if hired.
Dude, read the whole thread. Lots of good info here.
