I think the DOC rate of £1000 per hour is way out also. I know the local air ambulance costs per £1000 per hour to operate but thats the end cost to the charity and the various public donators, the cost to Bond themselves has to be less than that.
Incidentally to the person who was looking for offshore kit for a bo105, why not contact either Bond or Irish helicopters who operate two bo105's in the offshopre lighthouse support role and have done since 1969, they will surely know where to direct you to.
