I won't say which south coast airport just up the road from s/hampton last winter had it's only de-icer frozen up so it was usless, they had to pull the parked a/craft on the apron into the rising sun and turn them around B-B-Q fashion. I kid you not!! Nice one s/air.
About 14 yrs ago on a FR flight from BHX to DUB at about 9am the crew waited and waited for the deicer. At about 10.30 am it had got sufficiently warm and they finally turned up but as pilot remarked it was probably no longer needed as the ice was mostly gone but he then stated I'd rather not take the chance so they are going to do it.
