My favourite was a day the range was closed because 'the diver, he is a-sick'.
The yanks actually started the full rigmarole of filing flight plans to do the 2000' 'low level' route, one every twenty minutes (which was the max. allowed ISTR). The Italians were now faced with having to process these - real work(!). One hour later 'The range, she is a-open! The diver, he not sick'
