I think I have some information that could really help you out goob. It isn't raw data, but a mere collection of some personal experiences of mine.
First of all, I'm in OCS currently. Over my 9 weeks here so far, I've made friends with, and become familiar with many of the candidates (and now Ensigns in many cases) of classes 15-07, 16-07, 17-07, 18-07, 19-07, and 20-07. I was a candidate in both classes 19-07, and 20-07. So I think it is safe to say I observed a very large population of BDCPers (i'd say at least 75-100 or so). Of all of them, I can only thing of a handfull, but certainly no more than 10, that weren't caucasian.
So I have to say, based on what i've seen, there isn't any evidence whatsoever supporting your claim (that race plays a factor in selection).
As my recruiter (who was very seasoned and experienced) told me, it is all a game of timing and numbers. That's it. He's seen the most competitve candidates get turned away cold when things were tight, and candidates with weak packages selected mere months later.
Also, my selection fully supports this. I applied for BDCP back in 04. High astb score, outstanding LORs, and I had a 3.9 in Aerospace engineering at ERAU. I was president of a couple clubs, had flying experience, etc. Thought I had it in the bag. I was turned away cold for both pilot and NFO.
I reapplied 4 times. Last attempt I applied with a 3.0 gpa in management (much less competitive for many obvious reasons). I was selected within 2 weeks. My race didn't change.
Bottom line; unless this unusually high number of non caucasian BDCP selectees (in comparison to caucasian BDCP selectees) are getting trained somewhere other than OTCP, the argument that race is playing a significant role in the selection process these days simply has no merit.
-----End of analysis, beginning of personal opinion-----
I am not as educated as you in the arts of recruiting, nor about the background of the BDCP program. But unless i'm missing something major here, I think it is harmful to jump to such bold and dangerous conclusions.
There are so many factors and components that go into a BDCP selection. I remember taking the better part of a year to assemble all of them for my package. To ignore all of these factors and focus in on a 1/4 inch checkmarked box on one of the dozens of pages that comprise the package, and suggest that race is what it boils down to is in my humble opinion ignorant, and most importantly unfair to those non-caucasians that worked hard to be where they are today.
