The BBC news has just announced there has been yet another road accident (pedestrian fatalities x 4) involving a car being pursued by police vehicles.
Avoidance of this type of accident was one of the reasons police pursuits in UK were in my day (pre NPAS) often carried out from the air where possible. Obviously, with fewer aircraft now available, this type of accident is very likely to continue to occur, as it was in the bad old days before police helicopter air support was more in vogue.
