I do wish there was more stuff for the younger kids to be hands on involved in at Avalon. It was being on the wing of a DC-3 at age 6 that ignited the bug in me, and I'll never forget it.
WRT the JSF Helmet, considering the RAAF will only have 72 of them (one for each aircraft), I don't like anyone's chance other than the pilots and ALS crew getting their hands on them! Expensive piece of kit for sure, but when you consider what they can achieve and their cost relative to the entire program, probably worth it. I wonder how operable the aircraft is without it in the event of an inevitable U/S?
