I'm looking forward to congratulating Chris at this year's FNHT supporters' day!
He gave a fascinating and detailed account of the incident at last year's FNHT supporters' day. I'm sure there's a write-up somewhere but from what I remember he initially felt a vibration so initiated a precautionary landing but had no way of knowing that the aircraft was leaving smoke - though obvious to viewers on the ground. When the engine refused to provide power he considered baling out but took the option of retracting the gear to stretch the glide to the runway, popping the gear out at the last minute. He was only a couple of seconds away from the u/c locking down - so was unlucky - or very lucky, depending on your point of view!
