Hypersonic aircraft will fly from NYC to London in 90 minutes

Why a Mach 5 passenger plane is a crazy idea that might just work

Atlanta-based startup Hermeus hopes to develop a passenger airplane capable of reaching Mach 5, or 3,000 miles per hour, but is the prospect of building a hypersonic successor to Concorde merely a flight of fancy?

Hermeus, an Atlanta-based startup whose goal is to develop hypersonic aircraft, believes so. It's already testing a new type of engine it says will eventually be capable of reaching Mach 5 (over 3,000 mph).

Hermeus hopes to get it in the air for the first test flight before the decade is out, in 2029

That would be nice. Traveling for 21 hours from Pakistan to NYC is too much time.

Very nice! I wish I could take it to Costa Del Sol, Spain

They might get shut down over complaints of loud noise like the concorde.

travel time from Pakistan to NYC is not 21 hours.

Concord was shut down as the Airport windows used to get smashed due to loud noise etc

Unless they are making it electric it's not going to work

Direct flight is 14 hours but with stays and stuff it reaches 20ish hours

Won’t change the noise issue, the sonic boom doesn’t care if you are powered by jet fuel or electricity.

Which is why the Concorde never went supersonic overland.

Ok

Then they should fly like a car. Superfast after 10 minutes of departing and dead slow before 10 minutes of landing

Thought it was shut down because of the terrible crash?

At least, that's the main reason for its retirement that was widely reported.

The sonic boom is an aerodynamic force, Concorde flew at Mach 0.98 and only went supersonic over the oceans/seas.

The crash wasn’t the main factor, it was airbus ending it’s support program in the economic downturn post 9/11

yeah and so cannot compare an indirect flight with a direct flight.

I once saw a documentary on Concorde that stated that the sound waves were so powerful that they would shatter airport windows, that you need a long runway at the airport, that most airports would be unable to handle this plane, that reports of causing damage to public property due to the soundwave, that it would frequently lead to mechanical problems and costly to repair were some of the reasons for it being shut down.
