As a pile-on / slightly different perspective to this, I'll say that the debate isn't really over whether someone who is enlisted could perform the task - of course they could, and maybe they should. I do disagree that having enlisted drone operators is the panacea that internet message board comments abound would have us believe, though. The notion that they "couldn't hack" the mission is a red-herring.
The real issue is that enlisted drone operators would have an even greater incentive for getting out than the currently fielded solution does (i.e. the officer core). The reason for this is because the work is the same, but the pay differential for the same skill set on the outside is even larger for TSgt Joe Schmo than it is for Maj Umpdenuts. Hence, in what universe does a TSgt S (who's being paid $42K/yr) look at that contract drone salary and decide he's going to stick it out for the long haul, but Maj U (who's paid > $100K/yr) decides the stress is just too great, and jumps out to increase his pay and QOL to a lesser extent than the TSgt? If anything, having enlisted drone pilots (may) would only exacerbate the current retention issues facing the drone fleet.
If it was simply a matter of throwing flesh at the solution then the AF could send these motivated Es through OTS (for what, like $12K?), and probably have to deal with less "institutional" upheaval than "plan B"...
Pile on. SO's have a tough time with recruiting and retention. Can you imagine how competitive recruiting for so would instantly become if with 1000 RPA hours, a clean record, an a BA, so's had a direct path to ots/18x? People would be falling over themselves to cross train.
