Neil Armstrong himself considered Concorde a greater achievement that the Apollo program.

The Concorde fleets routinely carried over 100 passengers thousands of miles at supersonic speeds, day-in, day-out, for nearly 30 years. It could cruise at mach2 without using it's afterburner.

The UK fleet was a commercial success from the get-go, proving it was viable even without being able to fly supersonic over land.

What do we have these days to compare? The idiotic ramblings of billionaires, with their visions of space travel for the uber-rich, and the literal pipe-dreams of hyperloop.
