My guess would be it's an X-37B coming in for a landing:
Best guess yet and totally possible but they would be 2 weeks early by there estimations.
It wouldn't be that as it is similar to other aircraft in size
My understanding is the bigger the craft, the bigger the bubble, the louder the pop/boom
I'm going with a black world aircraft... A large black world aircraft
Possibly the SR-72 or other such large aircraft such as bombers, there is a new bomber to replace the B2 in the works also
Northrop says a "mannable" subsonic design could meet LRS requirements, while Lockheed favours supersonic and unmanned (Below)
But I'm thinking because of what witnesses reported it is possibly still larger
NASA is currently testing ways to reduce sonic booms and also testing to see which is acceptable IN California, Ohio, & Virginia, which is where some
of these reports where made
Overcoming this sonic boom prohibition has kept engineers busy at the four NASA centers that conduct aeronautics research in California, Ohio and
This rendering shows The Boeing Company's future supersonic advanced concept featuring two engines above the fuselage: NASA/Boeing, Since the maximum
acceptable loudness of a sonic boom is not specifically defined under the current FAA regulation,
NASA and its aviation partners have been researching ways to identify a loudness level that is acceptable to both the FAA and the public, and to
reduce the noise created by supersonic aircraft. Using cutting-edge testing that builds on previous supersonic research
NASA has been exploring “low-boom” aircraft designs, and other strategies that show promise for reducing sonic boom levels. Previous research by
NASA, the military and the aircraft industry has determined that a variety of factors, from the shape and position of aircraft components to the
propulsion system's characteristics, determine the make-up of a supersonic aircraft's sonic boom. Therefore, engineers are able to tune or “shape”
a boom signature through design to minimize the loudness of the boom it produces in flight.
The most recent possible supersonic aircraft designs reflect what's needed to meet NASA's low-boom requirements. These requirements specify targets
for boom loudness, aerodynamic efficiency, and airport noise for an N+2 —second generation beyond current technology — aircraft design that could
be flying by the years 2020 through 2025.
