I do remember before all this hi viz stuff starts that 2 aircrew walking across the flight line were struck by a runway snow blower when the driver didn't see them. Although they were injured, it was their good fortune that the machine had just broken a shear pin. The impeller drive in one of those things has around 600BHP.
After an excellent landing etc...
And the only person to be hit on Waddo's secure pan was wearing Hi Viz. Go figure.
