There have been no RC-135 accidents that were not attributable to anything other than pilot error
Well so you keep saying, but attributed by who? You? The USAF? Boeing? With all due respect none of those are proven impartial accident investigators. Indeed they seem to have as much partiality as the RAF and the MOD, who have a track record of finding by default the first people on the scene of an accident to be responsible for it. Pilot error saves a whole lot of trouble; to aircraft manufacturers, operators, and in particular to airworthiness authorities. Given the present military aircraft arrangements I wouldn't buy a used car, let alone an aircraft, from any of them on either side of the pond.
The most impartial review of 135 accidents easily available is Wikki (and doesn't that say a whole lot about where we're at?) With engine and tail separations alone a noted feature, you seem to demand a lot of your pilots and little of their superiors.
Self Regulation Doesn't Work and in Aviation It Kills!
