You really are a moron taking low level pot shots.
The truth is that the concord has nothing on the aviation accomplishments of the US. Why the fuck would we be jealous when we have been to the moon, built SR-71's (which are twice as fast as a Concorde), the F-22 and the B-2 bomber?
All are vastly superior aviation accomplishments. Fuck off limey with your hate you loser.
I grew up in Germany and then served there in the Army. Sonic booms were common place during the Cold War. I heard them countless times as interceptors scrambled to intercept Soviet planes.
BTW, this Russian bear aggression is nothing new.
