First and so far, only, Transonic-cruise airliner! Well, almost, since Concorde and the Tupolev were designed to go way faster but can of course go at that speed as well. And some of the faster subsonic airliners like the 777 (that 'long slope on its head', as DatamanA340 refers to it in the 777 vs 330 thread) incorporate a bit of the features needed in that flight regime.
