About 15 years ago, one of our Captains hit the boom of an ARFF firetruck with the right wingtip of a practically brand new 777 while taxiing to the gate on his fini flight.
The firetruck drivers had positioned their vehicles at specially pre-painted markings on both the sides of the taxiway leading into the ramp so that they could shoot a stream of water in a high arc over top the aircraft as a salute to the retiring Captain as he taxied to the gate.
The trouble was, the markings were painted to accommodate MD-11's, L-1011's and B-767's and no one had remembered to readjust them for the longer wingspans of our newly acquired 777's.
The poor Captain had flown his whole career and never so much had ever scratched an airplane and here he was now stopped short of the gate waiting to get the collision sorted out with his family and friends on board for his retirement flight.
Later, the company and FAA tried to blame the F/O for the mishap but ALPA rightly put up the defense that there was no possible way for the copilot to see the right wingtip's impending collision with the firetruck.
From that time on, I was more than happy with our company's policy that Captains did all the taxiing.
