Not on a Boeing?
Being presented with my lunch on a very quick turnround, fortunately at Base, with so many other matters requiring my attention, sloppy eating resulted in my fork slipping from my hand and bouncing across the control column, hitting something else and slithering, handle first, down the very slim gap between the nosewheel steering gear and the surround. It promptly disappeared. Talk about four candles.....!
So it seems as if it could, indeed, happen on a Boeing.
