Judging by the narrow marked areas compared against the original runway dimensions it seems that all the runways are in a poor state.
Vampires were ideal snow blowers during the winters we used to have. Keep the engine at around 9,000 rpm and let the tractor shove you around so that the jet efflux did the necessary. Four cleared half of Oakingtons 2,000 ft. runway in a morning, enough for one sweeping Vampire to disconnect from the tractor, take off and do a circuit and land.
After that it was two Dewents attached to a fuel bowser. It was not unknown for an untrained MT driver to overcook the throttles and sent the entire ensemble backwards through the bundu.
