The return of supersonic flight hinges on the race to solve one big hurdle | CNN (www.cnn.com)

The skies of Oklahoma City roared for six months in 1964 as military aircraft intentionally rattled the population below with a daily barrage of thunderous sonic booms. It was a controversial test — the consequences of which have lingered to this day.

Two approaches in the works could revolutionize air travel by making future supersonic passenger planes compliant with the FAA’s new noise rules: Colorado-based company Boom Supersonic, which is specifically mentioned in the FAA proposal, plans to use physics to prevent sonic booms from ever reaching the ground, regardless of plane design. NASA, on the other hand, is flying an experimental plane called X-59 that is specifically designed to reduce the intensity of the boom.

but air resistance is a bitch. You wanna go twice as fast, you need four times as much power

Unless your supersonic aircraft is up a lot higher than your subsonic one. Coffin corner is a different beast when you can go above Mach 1.

So perhaps this will work out as twice as fast for only 3 times the fuel. An acceptable tradeoff, perhaps.
