We use pig urine on land airfields, very strange stuff, its mixed up in a large vat on the back of a 7tonne lorry and heated through. When it gets sprayed on the tarmac/concrete it works like magic removing the snow and ice, on the aircraft it get pumped through a spray gun, it comes out looking like some one has sneezed all over the jet!

I should know because I got a back wash from the spray a few weeks back whilst I was spraying the ice on the wing of a 767 airliner! It doesn't taste or smell very nice, sweet and sickly taste but with a raw after taste of something nasty!!!
Weather update- Rain through out the night and a few broken showers over MPA, 6 deg C ground temp but with gusty winds knocking it down to 0 deg C.
A Landie broke down again and was taken back to the garages- hope they actually fix it this time, the replacement is slightly better- the starter motor actually kicks the engine over but still not instantly

and what was worse whilst I was changing Landies I brushed past a post whilst reversing and got a telling off from a 'jobsworth' in MT for being the third person that day that had hit the same post, to which I replied that perhaps he should do something about it instead of telling me off! Needless to say he was not happy with a airman telling a corporal how to do his job and walked away in a huff!
Oh well, we won't be getting a decent Landie now!
