Well, well !!
What goes round, comes round. See RN Wasps circa 60s,70s and rotor head flotation gear. Mind you, all this sort of namby-pamby stuff is for chaps who eat quiche.
Proper hiccopleeter fellas go and "enjoy" the 'Dunker' at Vernon so that they can cope with all this 'Which way is up?' stuff. Great joy!! Nostalgia is not what it used to be
