It used to be "ok" to drink and drive - the RAF only caught up in the past 15-20 years
Not so. Somewhere around 70-71 a decree came out that any officer who lost his/her licence as a result of a drink driving conviction would also lose their commission as well. I don't think anyone really believed it until an Air Commodore medic or dentist (can't remember which) was chucked out after a breathalyser conviction. Certainly made people think.
It was around that time that those living out were able to claim for a taxi fare home after a dining-in night as these were regarded as parades. Doubt if that still happens - indeed reading about non-existent mess life I wouldn't be surprised to read that dining-in nights no longer exist
