The then operator of the Scottish Air Ambulance always found it difficult to recruit people to the Islander operation largely due to the pathetic rates of pay which didn't reflect the necessity for superior basic flying skills and to compensate for the fact the fact that flying the Islander wasn't the ideal path to the left or right seat of a shiny jet.
The operation was always treated too casually although it generated proportionally more(?) incidents over the years than any other UK (or European ?) civil operation. IMHO there is no way that the pilot should have been allowed to operate after 30+ days off and a quick circuit. As it was I don't suppose he had a choice.
