Helicopter Hire did a lot of work with the police in the late 1970s... he gained a contract to run Enstrom's for the Met Police, initially from Elstree until one got attacked whilst out on the field [nothing new there then] and then the ops moved to the safer location of Lippitts Hill.
He used his ill fated Alouette II G-AWAP to provide early [Marconi] heli-tele operations for the BBC and various police operators. It started with the Mk 1 version [as developed in 1974 for the AAC Scout] externally mounted in a crude box then mounted the ball version as later seen on the Met 222s and Belgian police 330s. In 1982 HH gained the contract to provide most of the security air cover over the Papal visit .... again the Marconi turret but the difference was that at night the colour camera was changed for a [very] early FLIR camera..... Getting that out of the military was amazing in itself. There was a war on.... The secret may be that he did most of the development flying for Marconi [also Essex based] and that later included BO105 G-BFYA famous for numerous 'actions' including the Iranian Embassy Seige.
Did anyone ever write a book about him?
