That picture, and the implications of a failure mean I’ll be taking the slow, old fashioned route instead.

To land, the pilot cuts the engines and glides down to Earth before reigniting the regular engines before landing.

Pilot: "Uh, folks, we have a little problem. We're failing to reignite and as you know, with these wings of ours, we have a glide path of approximately straight down. Please prepare for a rough landing."

What could possibly go wrong!

Worked for Magellan.

So it’s only 49 years off?

Way to go out on a limb there. IOW- it’s just a couple of cool artist’s depiction.

Seaweed ?
What about my osembe crackers ?

Your trip will cost 5 times what it cost to fly on the Concorde.

And if the thing crashes.... I can only imagine.

Give or take.

[patton]

LOL! Must be a british pilot.

Just FYI...in about 7 yrs 4 1/2 months we will elect a very bad president.

Even if your jet engine burns “biofuel” it still puts out nearly as many combustion by-products products as regular jet fuels do. All it accomplishes is to enable someone to have warm fuzzy feelings about this without shoving a hamster up their butt.

Count the windows on that plane, figure the cost of this fantasy divided by the number of available seats, and estimate what a ticket might cost you, one way. 50-100 passengers on that flight?? No way.

And if you are going to fly at that altitude, the passengers will need some sort of space/pressure suit, because even the tiniest leak of air at that height would be horribly and painfully fatal to everyone who was not wearing a suit. In other words, you will not simply board the plane and take off like you were flying down to Miami...

Not to mention that the only aviation facilities I am aware of that have the ability to handle large amounts of cryogenic hydrogen and oxygen belong to NASA. To my knowledge there is no space launch or support facilities in either Paris or Tokyo, so that relegates this entire story to Science Fiction.

Great outline for a novella though....

"Just FYI...in about 7 yrs 4 1/2 months we will elect a very bad president AGAIN. "

Correcting your sentence for grammar and punctuation.

I'm helpful that way.

[Tijeras_Slim]

Paris to Tokyo in 2.5 hours

Yeah, but I'd still have to get to Paris or Tokyo.

[Sonny M]

bump.

Are you sure you got my sarcasm?

[steelyourfaith]

Thanx for the ping decimon !

 

Beam me to Planet Gore !

Worst case of blue balls I've ever seen.

Cheers!
