At the recent DASC Pre-season flying display symposium, it was announced that all flare releases have been outlawed. This decision was made as the manufacturers of the flare systems could not be certain that no debris would reach the ground following release. Any such debris could prove to be harzardous to persons and aircraft below.
Some of the most prominant users of flares at airshow have been written to by the UK MoD asking them not to employ flares at UK shows. At the symposium, it was also confirmed that this regulation affected the coastal airshows as well as those held over airfields.
