Re BRS; it is a matter of investment but also practice. I was based there in the 90s and recall one chaotic day in particular, with a snow mover moving snow from A to B and the next one that rocked up moved it back again; total confusion. Eventually took off bound for ABZ where the snow was much much worse and all the kit was moving in harmony, keeping runway and ramp clear. Relatively normal turn around and back to BRS chaos. So far as I could see much of the kit was the same it was the organisation.
