I think that time it was the airport tug, after Tonka wouldn't start. Maybe they went to best of three..?
The tug was because we had a hovercraft to move the forgings around between gantry crane runs. It was much easier to 'organise' things to be in the right place, when you could manoeuvre with more flexibility than only running on rails. This meant filling in the flange gaps in the inset rail lines, to avoid losing too much air. Just done with bits of wood, if someone could remember where they had been put after the last time the hovercraft was used...
Not twisting your ankle when cross the many tracks around the place was an important skill, particular outside. One morning, glancing down to be sure I was OK, I saw a foot, with a blue trainer on, flash in, as though to trip me. Ready to sort out my assailant, I spun around to find there was nobody at all there, And I was in the middle of an outside yard, with 100 feet of empty space around me - odd, but I just put the hallucination down to overwork.
Then, in the afternoon, I had a cup of tea and put my feet up, to reveal that I had a black leather safety shoe on one foot, and a blue suede trainer on the other...
