Whilst agreeing that the mid 70's is a strong contender, may I propose the late evening of 5th June, 1944 please? The RAF had the wherewithall and intent to give Adolfs lads a Sound Thrashing. Both qauntity and quality were in play; piston was reaching it's zenith, jets were evolving, weapons and tactics had reached a high level of maturity, manpower was massive. We had a close relationship with our allies and after succesfully seeing off the Beastly Hun a few years earlier - it was payback time.
