Snippets from their various press releases:

"the world’s first ever safe-landing mechanism, which in the event of a complete engine failure or malfunction, the aircraft will still safely land on ground or ocean, minimizing fatalities."

"up to 100x quieter than a helicopter,"

"The low noise is generated with the help of small propellers for landing and takeoff."

“the first-ever bladeless technology for managing the hypersonic aircraft."
(But it is only Mach 1.9, not hypersonic)

"As the plane aims to operate on net-zero carbon emission so it can achieve a length of 205 ft at a speed of MACH 1.9."
(Word salad)

Why won't these dreamers just talk with an aeronautical engineer ?

Realism is such a buzz-kill.

Does it get longer the faster it goes? Paging Michael Scott...

Concorde did get longer the faster (well, hotter) it went.

Strangely I read a length of 205ft as the range it can achieve at 1.9... :scratch: :doh:

You assume that producing a product is the goal.

Here is a New Atlas report on LEAP’s SST as well as its founder and CEO.

If you scroll down after reading that article (it’s worth the read) you’ll find this New Atlas article on the Bulgarian Batmobile, a 5,000+ horsepower, all-carbon fiber, electric sports car.

Peter ain’t got nuttin in these guys.

Well, at least I've found a cool new website to stimulate my imagination!

If I am remembering my useless relativity lessons properly, the aircraft will skew shorter the faster it goes until it has no length at all when reaching the speed of light.

Yup.

But if you just put numbers in the equations, it will get longer if the velocity is IMAGINARY - which seems amazingly appropriate in this case.

Yeah, but only from the perspective of an observer on the ground. And who cares what that guy thinks, he'll probably say it was struggling to climb, the engine sounded rough, and then it stalled.

remember these guys get money because they promise incredible results with some new technology and guys with too much money and little thought think they will make a billion if they put money in.

Remember the Eclipse and the Ecomotor.

especially if it looks strange the more money you can get.
