Couple of years ago UK National Grid asked me to look at live line and patrol stuff with 500's. basically was told by their flight department the 500 was crap. 355N was better and safer hanging a basket with 2 guys 100 to 150 ft under the helicopter ! Now forgive me here as I have never done live wire work ( would have had to buy in expertise ) but certainly have done long line work, how is it safer using a 355 with no floor window hanging a basket 150 ft below? Personally I think that would blow a risk assessment out the window !!! I have heard that there were not many volunteers for the basket and the 355 could only carry 20 mins of fuel to stay cat a - what a waste of money, mind you if you see what happens at Nat Grid it is par for the course
