A sixty five year old idea recycled

Quote:
People will soon be able to fly from city to city within minutes, rocket and car entrepreneur Elon Musk says.
Mr Musk made the promise at the International Astronautical Congress (IAC) in Adelaide, Australia.
A promotional video says the London-New York journey would take 29 minutes.
The British Interplanetary Society were making the same suggestions in an article sometime around 1952. I think a guy called A C Clark was involved! The idea then was to combine it with letter delivery service (you remember letters, like e mails on paper) One imagines that the fuel bill might be somewhat steep.

Arthur C. Clark was also predicting satellites, especially for communications use, back 65-70 years ago. The G forces of rocket travel might exclude some from that market, not to mention cost$.



MUSK: ROCKET TRAVEL ON EARTH!

FLY ANYWHERE IN UNDER HOUR...

To be more accurate artificial satellites had been predicted back in the 19th century - Clark's innovation was the concept of the geostationary satellite

Just to digress slightly, I can understand why Concorde was scrapped because of its age etc, but I can't understand why no aircraft company has ever built a replacement.
Aviation took a giant leap backwards when Concorde went.
"The fastest ever time for Concorde's Atlantic crossing and the fastest ever set by a passenger aircraft, was 2 hours 52 minutes.
This was set by Captain Leslie Scott and his crew onboard G-BOAD, flying from New York to London, on the 7th of February 1996."

Because Concorde, even with exorbitant ticket prices, had to be subsidized by the British and French government. It was too small a market for the price, and the fuel used was far too costly.
This is why Boeing went with the Dreamliner 787. Slightly faster, fuel efficient, but not so costly as to operate at a loss. Right now it is best on long flights where the speed and fuel efficiency pay off best.

As for Musk, I think he's finally gone insane.

Concorde was very !imited on where it was allowed to fly supersonic which cut out the profitable routes and any successor would have had the same problem

Yes Concorde was never a viable proposition so it had to go in the end, but it's still surprising that a replacement SST was never built, especially for routes across oceans where the sonic booms wouldn't bother anybody.
However there are times when new technology might not always be a good thing, such as the very expensive planned high-speed 200-mile rail route in Britain between London and Manchester.
Apart from the colossal expense it'll cause massive disruption to homes just to shave 20 minutes off the journey time, so a lot of people are saying it's just not worth it.
I tend to agree with them because 20 minutes is nothing; it'd be different if Britain was a massive continent where whole hours could be saved..

NASA Has a Way to Cut Your Flight Time in Half

The space agency’s supersonic plane design could be quiet enough to lift the long-standing ban on overland travel, if it makes it to production.
