Is this just an issue regarding flying suits or does it extend to the wearing of service uniform while "off base"?
As a former (fairly recent) member of the airforce I recall that the main reason for not being allowed to wear uniform off base was the terrorist threat from PIRA. Judging by the small amount of Northern Irelands politics that makes it as far as the Southern Hemisphere has most of that threat not now disappeared?
Or is it just a Grow Bag thing?
