Many years ago I was climbing the forward stairs of a B737 on a remote stand when I saw an unlighted, (unlit?), B727 reverse into the path of a catering truck, the centre engine finished up on the floor. Was very disapponited to hear much later that the driver of the truck was sacked and the tug crew, (no lights, no marshallers), were exonerated and the insurance paid out as though the truck was the guilty party!
