Tokyo to San Francisco in 5½ hours? If all goes well, yes

It’s been 50 years since the first Concorde took her maiden test flight, inaugurating the era of supersonic passenger travel, and almost 16 years since that era drew to a close, back in 2003. Since then we’ve had indulgent A380s and efficient 787s, but the truth is, we never really got over the Concorde. It’s still the one that got away, memorably beautiful if rather high-maintenance.
