CoolHand writes in with a story from Vox about efforts to bring back supersonic passenger jets:

One of the odd aspects of modern air travel is that it's not really getting any faster. Ever since British Airways retired its money-losing supersonic Concorde in 2003, airlines have generally stuck to top speeds of around 615 miles per hour. That'll get you from New York to San Francisco in five or six hours, depending on the winds, but you can't find a plane that will get you there significantly sooner.

We've largely learned to tolerate our slow, boring aircraft. But there's a compelling case that we shouldn't — that air travel should actually be much, much quicker.

Right now there are a host of energetic startups and NASA engineers working on sleek new supersonic jets that could fly twice as fast as today's commercial planes, if not faster. These jets would be major upgrades on the noisy, fuel-squandering Concordes of old, and they could be ready within the decade.

When you talk to people working on these super-fast planes, it's hard not to get swept up in the excitement. Take Blake Scholl, the CEO of Boom, a startup that's working with Virgin Galactic to put a new supersonic business jet into service by the early 2020s. He envisions a day when anyone could cross the Pacific or Atlantic in just a few short hours. "It changes how you think about the world," he tells me.

So what say you, Soylentils? Do the political, environmental, technical and economic challenges standing against these efforts outweigh the benefits of supersonic air travel? Should supersonic flights become common or even ubiquitous?
