I remember the Boeing Rep a few years ago (pre-binning UK MPA) challenging the very knowledgeable UK/US audience for a Maritime activity that could not be done from high level. The shouts came thick and fast especially when the tricky concept of cloud came up:
'Drop a tight buoy pattern'
'Read a ship's name'
'Drop a dingy to a survivor'
'Take a photograph'
'Lase for a weapon'
'Perform a show of force'
'FLIR search'
'Discriminate a survivor from wreckage'
'Spot an oil slick'
'Spot a vessel on fire'
'Spot deployed fishing nets'
'Perform a MAD run'
'Discriminate between blue ships and red ones'
On and on it went and the poor chap looked quite upset. He didn't even challenge the bloke who shouted 'strafing seals'.
