I had a similar experience at Gatwick last year, having arrived from a long-haul flight ... which I do several times a year without even thinking about it. Left Arrivals for a kerbside cigarette in the Smoking Zone, and suddenly just folded up gracefully to the floor ... my descent being controlled by the OH. It came out of nowhere, and not encountered before or since. SCARY.
