We do indeed live in unprecedented times as I find myself agreeing with pr00ne! They should have done away with saluting long ago, except perhaps for the Stn Cdr & Air Ranks, and on the parade square. As an aged PAS Flt Lt I could spot the young JOs a long way off trying to discern my rank versus the grey hair & often hedge their bets by saluting, I even once encountered a Sqn Ldr who threw up a salute as at my advanced age I surely had to be at least a Wingco? All of it rather tiresome & frankly unnecessary, you could still be polite & say ‘good morning’, it worked well enough on ops where no one saluted.
