tinaferrara: what is a bone dome,a new one on me
I Mike

the shitehawk will clarify in FULL
Bone Dome is standard ERK slang and humour for aircrew headgear.
Some of us in the REAL Airforce ( those tradse who workd onthe aircraft) as opposed to shiny arses and gash trades (Royal Air Force)
wore them when on flying duties on air tests etc as of necessity.
We still use it to describe Motorcycle helmets from which they were originally developed in the late 1950's and its our irreverent term used for baldies of both sexes (even ourselves) - We don't care if civvies use it too - They however, just have to accept our language, humour and either join in or sod off
NOTE to any PC must nots and human rights lecturers - WE would NEVER knowing allow anyone ion our presence to use it to describe anyone on medical treatment or anyone who suffered from allopecia (if that is how its spelt)
