I remember going up to the viewing deck at FRA some years ago with my lad who was beginning to show an interest in aviation (he is now doing his ATPL).
One thing that raised my eyebrows that day was the sheer speed at which the LH tug drivers were pushing aircraft back including 747s. Michael Schumaker would have found it difficult to keep up.
I have no idea of how many thousands of times I have been pushed back since 1978 and I was quite frankly astonished.
Has anyone else out there noticed this phenomenon?
