And the environmental impact is... what? Amazing that this is not a consideration, especially since we are now in emergency territory: http://www.theguardian.com/environment/2016/mar/21/global-wa... It's great for you to leave SF in the morning, go to Sydney to watch the opera and be back in SF by midnight. But is the environmental impact of you doing that worth it for everyone else?

I'm always intrigued to see what sorts of comments are so transgressive as to require green-bean HN accounts.

Earlier quoted context omitted.

There's a steep difference in the acceptable safety of a space vehicle and of a commercial airliner.

There's also a steep difference in the tolerances you can permit. A rocket -- especially one with any hope of reusability -- is something that can't be built without getting very very close to the maximum tolerances possible within the bounds of physics. Look at the temperature differentials in a rocket engine for example... it involves nearly instantaneous transitions from deep cryptogenic temperatures to ones far b…

It is easier to build a rocket, than supersonic commercial airliner. Soviets build many rockets, but practically failed on commercial airliner. Americans gave up.

How can they discuss cost and dates when it sounds like they don't even have firm plans on the engine? The promise of Boom is very compelling and good luck to them, but it's just a dream right now.

If it was as easy as the founder makes it sound, Boeing would already be doing it.

Pretty amazing that materials science (lighter, carbon-fiber aircraft; hotter, more efficient/powerful turbines) has made this economic. Concorde never was. NYC-LON seems like the one market where this enables something fundamentally new (well, Concorde did); single-day business trips between two major business centers which were otherwise a full day apart. Transpacific flights would be nice, too, but cutting an alre…

> single-day business trips between two major business centers which were otherwise a full day apart. Was the LON-NYC flight time the problem, though? I think that to go door-to-door right now you spend 50% of the time in the air and the other 50% on the ground. With this company, you'll be spending 3.5 hours in the air and 8 hours getting to and from airports and through security.

It depends on the airport that you are travelling from. London City has famously fast security, currently you can check-in upto 15 minutes before the scheduled time of departure for a flight to New York. [1]

I believe the problem with those was always the sonic boom created by flying at > 1 Mach. It shattered windows on the ground. Could be wrong tho

Supersonic flight is banned over populated areas. I'm not sure if it's from shattering windows or not.

Is there any reason you can't fly subsonic over land, then accelerate to supersonic over the ocean?

Sorry but is "Boom" really a good name for an aircraft company? I get it's supersonic, but my first association was an exploding airplane.

It gets scarier, they compare it to the Concorde based on price:

Unlike Concorde, flying Boom is affordable—the same price as business class.

Ok, so the Concorde had some critical engineering faults, making it cheaper definitely sounds more secure.

It describes their values as something like 'fly long distance in the morning, do a bunch of meetings there, and be back before the end of the day'. Does it make sense to travel 20,000km on one day to make a bunch of meetings, spending 15,000$? I feel that better tele-presence just makes more sense.

If being there in person gives you a 2% better chance to close a million dollar deal, then it already makes sense to blow $20k on the ticket.

The telepresence rooms we have at our corp. are 100's of thousands for a room. And you have to have another room on the other end. If it will be a consistent meeting then it makes sense to set them up but for one off meetings at different locations then the cost is not justified.

I do see a stereoscopic (3D) 360 VR future someday but we have a ways to go to get the 'presence' of that down to realism still.
