CirrusF - you are quite correct. It is a pity that the word 'drift' came into play, really, although one assumes that the original question was about a hover relative to the ground? There are, of course, 2 sorts of 'high hover', both extremely difficult to achieve in a Harrier, the 'relative to the airmass' (ie zero airspeed) one being impossible to identify due to lack of an airspeed reading below 30kts and both 'dodgy' due to intake momentum drag. Best left to the experts like JF etc. I expect GeeRam has by now got bored and sideslipped his way back to the pub...........
