Thanks if789, consider this..if he was placed in induced coma, quite a serious decision, it is posssible CT may have shown diffuse one sided swelling which may have been attributed to head injury, particularly if there had been localising signs, ie pupil size. This may have been residual evidence of a dense transient stroke. Reading from the fj boys, the throttle is not advanced sufficiently at the start of the manoevre, if it is on the left this suggests left sided weaknesss, which may also suggest the left roll as with only a right side functioning the chap would feel lopsided and nudge the stick to the left, if right handed, and possibly a left visual field defect as well. I can't complete the analysis as with all the upside down and roll even my left/right is confused.
