I don't doubt this story. I recall an interview just after the AbuGrieb flap erupted. They were asking a former spook about what sort of methods were used for extracting information. One of the tactics that was cited, was that they would blindfold the prisoner, fly him around in circles for awhile, then land at the same place they left from. They would then take the prisoner into a room where there would be US officials dressed as whichever country they wanted the prisoner to think they had flown him to, complete with flags of the "host" country and such. The whole purpose was to lend credibilty to threats of torture by making the prisoner believe he was in a country that actually allowed torture tactics. All this and they didn't even have to jolt him once. The psy-ops guys are tricky, eh?
I would believe that...
