1977 Trooping the Colour Flypast at 1:50:00 onwards, however note that the commentator places Coningsby to the north west of Lincoln, so they were not that good back then except for the late Raymond Baxter. As for the producers, none of them in my living memory have been any good as these displays, be it ground displays (QCS / Kings Troop RHA /Etc) or flypasts. They always spend most of their time focused on close ups when the display is designed to be seen a distance.
