Helichoppers have many uses in the electrical field and ....... others. In the old British Aluminium smelter at Invergordon, NOSHEB periodically patrolled the transmission lines and the hub using thermal imaging; they also showed cracks in the 6 pot room chimneys, these were only about 4 years old at the time. This had to be kept quiet from the unions.
