This looks very cool. I was so disappointed by Concorde never really gaining enough popularity to drive costs down to a reasonable level.

I wonder what they mean by "affordable"; the article says the Boom XB-1 carries 55 passengers at high capacity, but a Boeing 787-8 Dreamliner for example can cram 335 passengers. Either way this is great and if it gains traction costs will inevitably go down, but I wonder what we are talking about price wise in the immediate future.
