This is a real Mayday.
Light aircraft (say PA28) flying at night from Ireland to Southern England. Approaching English coast the pilot is disturbed by the low readings on both fuel gauges. To satisfy himself this is an error he switches to the emptier tank. Shortly the engine dies. He switches to the other tank. Not many minutes to go now.
Mayday Mayday Mayday.
Unbeknown to him a baffle has moved in the silencer and fuel consumption has doubled.
D&D don't seem to do much. They simply tell him who is open (say Valley), freqencies, direction miles-to-go, and make all the necessary arrangements. OK he or others should have been able to do the same things. But this is an emergency and every second is precious. The professionals are fast, accurate and don't waste a single syllable of airtime. They know the pilot is under deadly pressure and fighting to save lives.
They all make it with not a moment to spare.
If this sort of thing requires a bit of practice pan. I think it's worth it.
