I would really think that environmental concerns would ground a supersonic commercial passenger aircraft, until those problems are overcome - most likely with a breakthrough in technology.

Do you mean the noise, or the energy requirements? The former can be dealt with, I think, or at least greatly limited (and flight paths can be kept to areas tolerant of a bit of noise). The latter can't really a commonly held concern it seems, or we'd already be trying to cut back on the tremendous amount of regular flying that happens every day now.

  Parent is probably referring to the ozone layer depletion caused by the Concorde and similar high-altitude jets [1]. [1] http://science.sciencemag.org/content/270/5233/70 http://science.sciencemag.org/content/270/5233/70

Yes. Hence no Jetson practical, pervasive flying cars either. For point-to-point bulk transport, it’s more efficient to have dedicated low pressure tunnels with maglev or similar. All that petro burning will look incredibly awful in 50 years, if not now.

  Good luck getting the land rights for all those tubes.
