At Gutersloh in winter we could have yellow colour states lasting for weeks. We used to launch and “grobble” our way around when it went up from colour state red (no flying).
One snowy day, during a colour state red, we heard on the squadron that a certain Puma (U.K. based but not the usual squadron) on a mission had just called up for a refuel but it had been denied landing request due to the airfield weather state. The crew insisted that they urgently needed to come in for fuel but were then informed that the station commander had been consulted and had personally denied them landing permission at his airfield. A short time later a Puma appeared out of the snow and landed on the sports field just across the public road, outside the main gate. The crew marched across to the guard room and requested the use of a telephone for a call to U.K. A very short time later the Station Commander received a mainly one way telephone call from a certain office back in Blighty, after which a bowser was sent across the road in very short order and the Puma soon continued on its merry way.
Stumblefingers might be able to confirm or correct my recollection.
