No info on incident but would not be surprised ,we quite often have to negotiate several other aircraft on ramp ,then they manage to squeeze in an Atr ,part of the problem is that too many "helping" hands are waving at you wether to indicate clearance or just waving ! When you are being pushed back you really are in the hands of the tug driver ,just along for the ride ,the freight ramp is an accident waiting to happen often the case 3 747s,Md11,Dc10,B727,Atr,very dangerous place for aircraft and people.
