London to New York in 3.5 hours: Mini-Concorde Baby Boom plane that will travel at 1,687mph

Daily Mail:

Supersonic air travel could be making a return if a plane that aims to replace Concorde takes to the skies.

Richard Branson-backed Boom Supersonic expects a prototype of its passenger plane to make its first test flight by the end of this year.

The firm this week came a step closer to that goal after announcing a 'milestone' engine delivery for the two-seater, known as XB-1, or 'Baby Boom'

'Baby Boom' is a 1,687mph (2,716kph) demonstrator jet designed to test the firm's supersonic technology that could take passengers from London to New York in just 3.5 hours - around half the time it currently takes.

1. Global Warming emissions?

How much more can we take?

4. Will a 3.5 hr jet trip make more emissions then a 7hr jet trip?

People are still going to travel.

2. Is anyone considering how this will impact climate change?

Faster faster faster at the expense of the environment is so very 20th century.

Hopefully the people engineering this have its environmental impact in mind.

3. We have the technology and the engineering to figure out how much to tax them on emissions

That is if we can figure out how much each milliliter of petroleum fuel costs in the degradation of our biosphere. I think we are only scratching the surface of how screwed we are on that account.

My car is electric/battery operated Chevy Bolt, the house is run on solar power and the largest portion of my time at work is comprised of keeping diesel trucks emissions compliant. Still, I have this feeling the race we are running in is not going well. In that race, we are still losing ground faster than we know.

5. This could be a carbon neutral innovation

But it won’t be cheap
