Earlier quoted context omitted.
> Supersonic passenger aircraft were operated profitably Were they? IIRC joint project by British and French national airlines, they expected to sell loads, hardly anyone wanted to buy the planes, the two airlines kept them flying out of government embarassment.
should probably spell it out: _it wasn't allowed to get to supersonic speed_. Same way we dont _allow_ eugenics.
Over the Atlantic? Nah, the problem was it was very expensive and not a great experience for the people rich enough to afford it.
The US company trying to bring supersonic back are not only focussed on the flight speed, but also the entire customer experience.
