Now if you're talking dry power super-cruise then the old F3 could do that as well - it had to be one of the new ones, without pylons and you needed to be at about 5,000ft if I recall correctly.
Don't get me wrong, you needed a crack of burner to get 'super' but then if you had a slippery jet then it could sustain 1.05M-1.1M.
Not as impressive as Concorde, but impressive all the same.
