When I worked at MAN, handled a one a/c outfit with a Banderante operating MAN-NWI or something like that. It was being marshelled, and the prop struck one of those red/white metal barrier things on wheels.
Was a right who-har between the airline and the airport about who was responsible as the marsheller was indicating the a/c to turn, but the a/c did not have the turn radius as tight as the marsheller wanted it to turn !!.
Never actually found out who paid out in the end, guess it was the airlines as they always seem to have to foot the bill for Airport Authority mistakes/inadequacies !!.
