Back in the Fifties the Royal Navy towed a vampire, mounted on a dolly
to raise the nose, around the runways and taxiways to clear snow.
The RAF developed this further my mounting two Derwents on a trolley
which was pushed around by a Bowser, called MRD, Motorised Runway De-
Icer. This worked well unless the melted snow/ice refroze before the
bowser had passed over it. When that happened the bowser quickly
became jet propelled, in reverse. Care also had to be taken with
asphalt surfaces, for obvious reasons.

Santa Pod raaceway also used a Derwent or Ghost, can't remember which,
mounted on a Lorry to heat up the burn-off/start area.
