Ops, I remember John Handley but not the Stansted event.
There was a Stansted event that ATCO may remember. The Airspeed Amabassadors had a quite large nose cone that was hinged at the top and had a toggle type fastener at the bottom. It was access for the hydraulic sysytems and some radio equipment. Normally it was locked closed of course but in normal flight airflow kept it closed anyway. The aircraft departed Luton for crew training. I think that the captain was Stezeyak ? and Liz Overbury was copilot training. All went well until the stall !! The cone opened fully and smashed against the windshield. Quite a mess and of course the drag/ turbulence must have been pretty daunting!. Anyway they diverted to Stansted and landed OK. !
