Really?
"I have always heard its the other way with Perisher. It's the only bit of fishead training that actually comes close to standard aircrew training pressure."
Really?? I don't think it's really that simple. Would you say that FNO or Spec N course is easier? Perisher is widely acknowledged as the hardest naval course in the world. I think it more than "comes close" as you put it. Witness the recent attempt of one (nameless) ex-frontline O on X Course (a course that my spaniel could pass). Snot, tears, left mob.
I don't want to get into a pointless debate over this - but its probably worth remembering that most RN Officers have a tough job which generally requires tough training. To be fair to fisheads - aviators rarely see the one-armed paper hanging routine on the Bridge as you are usually creating it by being airborne.
Alright, not pussers.
