Zetec, happened in Maritime from time to time. Win Harris at ISK wanted a photo of a Nimrod over the Kiev. Now that needs two Nimrods but by definition you only had one MPA in a given area at a time.
Permission was duly granted but when they arrived it was to find a P3 already on station. So they got their Nimrod photo and the P3 asked if they could do the same so round and round they went until a Bear turned up.
Round and round they went again with the aircraft all swapping positions to pose for photos.
