As I said HB - I have no objection to anyone wanting to wear a helmet if you think that it will make your North Sea flying any safer. I just think that it is OTT.Of the recent NS accidents that I know of a helmet would have made little difference to the crews concerned.
I expect to be firefighting again later this year and will be wearing my Alpha as will be spending most of the time below 200' dodging, trees, hills, birds, other aircraft and sitting in a 50' hover at 90% TQ. When I get back offshore it will go back in the attic. My choice.
As regards noise protection - WHAT DID YOU SAY??
