FLORIDA, USA - NASA wants to take commercial passengers from New York to London in around 90 minutes.

The space agency announced that it has been exploring “the business case for supersonic passenger air travel”.

It promises “blistering speeds” between Mach 2 and Mach 4, or from roughly 1,535 to 3,045 miles per hour (mph) — easily over twice as fast as an F/A-18 fighter jet’s top speed of Mach 1.8 or 1,190 mph, said the Daily Mail.

This would be almost twice as fast as Concorde, noted the paper.
