I nearly drove an engine into an Airbridge at a well know Indian airport ( the now changed name suppressed to prevent the innocent ) where self-parking by the pilot was the procedure, and the first person to enter the flightdeck was a senior ground crew member who looked at the self-marshalling lights and said - with accompanying wobbling of the head - " the lights are on, it wasn't our fault "
I never said it was your fault, I replied, but you had a crew of men watching, and not one even tried to intervene to stop me, a simple crossed arms above the head from anyone would have been sufficient for me to stop and at least ask why, they may not be qualified marshallers but did no-one have enough commonsense to even cry "stop" ? Were you all going to stand and watch me drive into the bridge regardless ? Such fun.
