Supersonic Technologies, Inc. ("SuperTech") is developing a supersonic business jet, and the first flight test aircraft is nearing completion. SuperTech wants to operate its flight test program out of the Grant County International Airport near Moses Lake, Washington, and needs a high-altitude supersonic flight corridor in the nearby airspace to enable safe flight testing without risk to other air traffic.

How should the company go about obtaining the needed airspace designation?

Some online research would probably help you answer this scenario.
