Supersonic air travel is finally coming back by Verge Science

I'm lucky enough to have been within metres of a Concord and I still remember when it retired and a model was placed outside Heathrow. It became an unattainable thing that you put on your bucket list and I was disappointed when British Airways decide not let Virgin Atlantic take on the Concorde brand.

Something that I was not aware of was the amount of fuel required to achieve supersonic travel. I guess it's obvious but the figures are much higher than I'd have ever thought they would be.
