Hermeus, Mach 5

nothing too miraculous, they say :).

Hermeus announces plan to build the fastest aircraft in the world. We want to do engineering, not science.

They say.

If I were in New York I would not want to go to Paris no matter how quickly.

The Hermeus declared aim of "up to Mach 5" seems a bit over the top to me, with the high thermal heating due to skin friction apparently to be dealt with by extensive use of titanium for the primary structure. I wonder whether that might prove a step too far perhaps, on grounds of high cost and potential fabrication problems, using a less than conventional material for vital components, on a large scale. I happen to have a couple of dental implants made of titanium, in which the metal embedded in my jaw cost me oodles of cash for such a small quantity, although much of that went on the highly skilled orthodontics of my dental surgeon of course, but despite that, I do wonder whether big and complex components on an aircraft can be produced which behave in service as well as my little implants! ;)))

The "Boom Supersonic" proposals for a Mach 2.2 machine would probably still be possible using conventional aluminium alloys like Concorde, producing a modest (and maybe more achievable) 10% speed increase over the proven Concorde service experience. If I was a betting man (I'm not), then I would plump for the Boom Supersonic project. But first, they would have to change that name, I mean to say!! :)

GM named their first electric car: the 'Impact'.

They didn't sell any.

"Isn't a Mach 5 aircraft difficult to fly requiring really expert pilots?".
"Don't worry about it Sir, the computers take care of all of the flying activities".
"Could I get a ticket refund please"'

You wouldn't find me in either of those places so no use to me.

So how fast can your teeth go 603DX?

If you travelled from Paris to NYC at Mach5 you'd arrive long before you departed.

There would be no proof that you'd travelled.

Refunds please!
One thing you can say for the French, when civilization falls they have less far to fall than everyone else.

Hopefully, they would just about keep pace with the rest of me ... :D

It would be a bugger trying to chase them down the cabin.

Once had clients arrive here but only the wife got off the ship. Her husband had lost his teeth and couldn't remember the cabin number. They do not delay departures for any reason. I spoke to the captain. He was so amused that he delayed the departure. They were located. Used to fly with a captain who stayed in a caravan near Gatwick. He arrived one day in the winter with his false teeth frozen into a glass of water in his nav bag. They defrosted on the flight deck.

Is this a case of "The hurrier I go, the behinder I get."?
