Can Boom Supersonic Succeed Where the Concorde Failed?

Can anybody tell how such a plane will sound like over land? Growing up in Europe in the 90s, we regularly saw fighter jets doing maneuver and we called the noise they make a sonic boom: a loud, scratching and thundering noise that seems to come from the wrong direction. But I've also heard that planes almost never flew supersonic over civilian areas and an actual sonic boom sounds like a double clap, and is much mor…

Am I the only one here thinking this is an unwanted future ? Aerospace is already profiting to few rich people on earth and represents 2% of global emissions and this is saying "well we need to go faster consuming yet huge amount of fuel" for the wealthiest. Please stop these technos solutionists gadget and start to think real problems like the climate crisis.

This is 100% correct. The last thing we need is more inefficient aviation for the super-rich.

Earlier quoted context omitted.

What do you mean? Airbus planes have been using software very heavily ( fly by wire for instance) since the first models, and recent ones ( A350) have pretty serious server rooms onboard. Just because Boeing are incompetent and criminally negligible doesn't mean that airplanes shouldn't use any software.

There's a view that over reliance on software contributed to the total loss of flight AF447 (since pilots were not sufficiently experienced in how to fly the plane in the various fallback modes to be able to react appropriately in an emergency).

Can supersonic aircraft be as big as the 747 etc jumbos without much worse energy requirements? Or does the fuel consumption rise by a factor? I can see the Concorde had almost mach2 as top speed? Is there another Sonic boom at mach2,3 etc? Unless it's a fuel efficient mach3, there's not much point to it, most flying time improvements should be done on checking in and boarding, the flight itself for flights less than…

"Boom is leveraging advances in engine design that yield greater fuel efficiency, which will mean cheaper ticket prices. But they aren’t stopping there. Boom plans to use fuel made from carbon removed from the atmosphere, meaning that supersonic travel will be carbon neutral from day one." You can have cheap tickets and don't give a shit about the climate or you can claim you use extra expensive synfuels made from ca…
