late as usual, but, as far as speed is concerned, I'll go for the Concorde, even if it's not flying anymore (and not only because the avatar image and location says it all <g>).
I don't know for US jet brands, but here, we'll go for Dassault's jets, starting with the Falcon, the most sold private and/ or corporated jet (at least, last time I checked
). The
Falcon 7X is their last and fastest trijet so far. With a range of 10,556 km and reaches Mach 0,80.
And as I don't suppose you want to take it on the military side, I'll stop there.
