TC
A risk assessment would have been done for the job !
Quite frankly the chances of an engine going bang and everyone getting killed is pretty remote. Probably a greater chance of being killed in the mini bus to the helicopter.
I am afraid to say it is the bloody ridiculous H and S we are going down will shortly mean we can't go out of our house, oh no wait a minute I will become obese and die early, what are we to do TC ???
