That means the industry has a serious chicken-and-egg problem: No one will fund a plane that may not be allowed to fly, and the regulations won't change until a plane is built.
That statement alone has probably already sealed this aircraft's fate.
However, some good things can come from projects like this. As mmartinfan wrote:
Lockheed Martin Skunk Works is working on a biz jet* engine that will go supersonic but not create a "sonic boom". Its only a matter of if its economically do-able for the civilian market.
* Biz Jet engine being worked on now. So we know then the military has already looked into it!
If any company, or design office, can do it it will be the Skunk Works. They designed the worlds most beautiful airplane, the SR-71, to fly higher-FL800+, and faster-Mach 3+, than any other air-breathing aircraft. They did it with slide rules, not computers, and nothing since then has even come close to equaling it's performance. I also agree with the statement that if they are working on the civilian version that the military version may be at least in the test stages.
