If 'involved' means crew and passengers, apart from road travel the number of fatalities to 3rd parties is relatively insignificant in most modes of transport.
'Relatively' is the key factor in that helicopter transport is relatively insignificant in any of hours/passengers/trips/distance travelled in comparison with the other modes. So Helinut's claim is statiscically weak.
Incidentally would Helinut count HLOs as 'involved'? They are in the global sense but they are very definately 3rd parties to the aircraft and occupants. There have been a few gruesome fatalities on decks...
Having said that I totally agree that helicopters, through SAR, air ambulance and other missions have made 'a unique contribution to the safety and wellbeing of those not involved with them' and that is a message we should sing from the rooftops at every opportunity.
If FlyCumbria is a NIMBY more worried about house prices than safety, then I suspect that most of the replies (apart from Helo's and Helinut's) will have reinforced a determination to fight this Cumbrian operation.
