#2Don't editorialize the headline. The article is much more nuanced than the headline suggests and it belittles an amazing achievement.

#3I assume the reduction in sonic boom is a result of the shape of the aircraft. Does anyone have any ideas on what these new shapes could look like? Links?

#4At 70PNLdB, I doubt anyone in their car could hear it. In fact pretty much only rural quiet areas will hear it. Though I'm sure there's going to be some "concerned citizens" that claim that the sonic booms are causing their children migraines, or something similar.
Still, living at one end of Canada and having friends at the other end, I'm excited for the possibility quiet overland supersonic flight.

Could this press release be related to this other one?

Maybe these?

This has a small image of a test vehicle: http://www.nasa.gov/missions/research/sonic_booms.html

I really want planes to look like the ones in the Wired article.

#8"Boom is proportional to weight, and a small supersonic business is likely to meet that level"
Really? I would expect it to be relaated to size and shape.

70 PNL dB is fairly loud, it will be very noticeable in urban areas and extremely disruptive in rural areas. 65 dB Ldn is the target for normal aircraft and most experts agree that limit is way too high.
The research represents a significant decrease in noise from supersonic aircraft, but we're a long way from "quiet."

Well, it's proportional to volume of displaced air, which should scale more or less linearly with the empty weight of an airplane.
