Let's put out some clarification here:

99.9% of Army aviators were trained initially (by the Army) as Rotary Wing pilots.

As greggo said, MAJ Gray is no longer the contact, but I believe the number posted earlier should still work.

The USAR is hurting for FW pilots. 75% of my unit is currently deployed. I just came back, although not by choice (medical).

In the past, hiring was left up to the individual units. That seems to be changing. It appears that the 11th Aviation Command (the command responsible for the majority of Army Reserve Aviation) is trying to centralize the hiring process. They've taken two guys from my company who are currently in flight school and reassigned them to rotary positions. We've fought the good fight to keep them, but lost. In other words, there is apparently no guarantee that getting "hired" by a USAR FW unit will result in you flying FW. We will certainly try to make that happen, but no guarantees.

Any specific questions, send me a PM. Things are in flux right now WRT hiring practices, but I can try to help if you're interested in USAR FW.
