I’ll be super excited to have low-to-null-boom supersonic transcontinental flights! But if this becomes a passenger plane, what kind of fuel efficiency would that have? Are supersonic aircraft more or less efficient (oranges and apples I presume).

The attached image of the assembly has a nice easter egg:

Apart from the Aerion as2 i dont think there are many other credible supersonic aircraft in development other than the Nasa one. Concorde, other than the booms, had engines so loud, and i mean insanely loud they would not be popular these days. I remember covering my ears as it flew overhead.

I do find Elon Musks frequent mentions of a vtol ss aircraft quite interesting. Electric engines would not have the same issues at high altitude as conventional ones. Battery density is starting to get in the right area to make this feasible.

He is frequently distainful of flying cars but one logical conclusion of this is indeed potentially flying cars (Tesla secret projects anyone?). When you think about how much of the world is inaccessible, one of these would make a great thunderbirds style exploration vehicle ( provided it had a large expandible solar array stowed somehow) . Fancy a trip to the Kamchatka ground zero? No problem! I wonder whether aerodynamically they would not need to be so concorde like and maybe just bullet shaped. Perhaps on Mars you could have supersonic blimps

Is anyone else around the world working on quiet supersonic passenger jets?

Perhaps I'm in the minority, but I'm concerned that commercial-supersonic will be a net-negative in my life.

I'm assuming that, as with the Concords, most of the benefit for supersonic travel would be to very wealthy individuals and corporations. But everybody living/working beneath the flight path would have to endure the added noise pollution.

I'm very impressed that they managed to keep it going for so long.

It will be good to dispel the ideological status quo in aeronautics community that "SST is dead and buried"

+1 for the googly eyes and mustache on the forward bulkhead...

(dunno if that's what it's called, it was the name that sort of felt most right)

Looks like its landing on Tattoine, which is appropriate for that thing.

How many seats?
