The Brilliant Buzzard, also known as the Mothership and Super Valkyrie is thought to be a huge aircraft with a wingspan of two hundred feet or so which actually launches smaller reconnaissance craft. Sightings of this delta winged craft first began in the early nineties. Some believe that it and the Aurora are one and the same.
Characteristics:
Forward fuselage resembling the SR-71 with a blended chine (intersection between bottom and sides)
Large delta wing with rectangular underwing engines
Wingtip mounted verticle stabilizers
Dark leading edges and dark, rectangular exhausts
A prominent "hump" rising from the blended fuselage and centered over the large delta wing
Some observers saw a prominent, low aspect ratio canard mounted close to the nose, while others saw no canard at all
Some observers heard a rumbling sound at low speeds
Light-colored top and bottom surfaces, with dark leading and trailing edges
Here is a computer-generated image of what it could look like:
This program operated under the code-name Aurora, another black plane that is thought to exist. This aircraft is rumored to be used to launch other, normal-sized aircraft to a suitable altitude. It is designed to achieve high velocities (Mach 3) by an efficient integration of propulsion and aerodynamics. Nothing is known about the aircraft's propulsion, but it is rumored to use Pulse Wave Detonation Engines (PWDEs).
The Brilliant Buzzard could either have been built by Lockheed Martin or Boeing.
Sightings:
On September 13 and October 3, 1990, sightings of the aircraft were made at Mojhave, near Edwards Air Force Base (AFB).
Another sighting occured north of Edwards AFB in April 1991.
On May 10, 1992, a journalist with CNN saw the plane flying near Atlanta, Georgia.
On July 12 at 11:45p.m. near Lockheed's Hellendale Facility and because it coincided with a severe thunderstorm in the Groom Lake area, speculation arose that an emergency divert had taken place.
An indication as to the aircraft's manufacturer came on January 6, 1992, when there was a sighting of an SR-71 shaped forward fuselage section being loaded onto a C-5 transport plane at the Lockheed Skunk Works facility in Burbank, California. It was about 65 to 75 feet long and 10 feet high. The C-5 was bound for Boeing Field in Seattle.
At 1:45p.m. on August 5, 1992, aUnited Airlines 747 crew reported a near miss with an unknown aircraft as the airliner headed out of Los Angeles International Airport. The airliner was in the vacinity of Georges AFB, California, when the 747's Traffic Alert and Collision Avoidance System (TCAS) warned the flight crew that an aircraft was approaching at high speed. The unidentified aircraft flew past the 747 about 500-1000 feet below it at high supersonic speed. The UFO was described as having a lifting-body configuration, much like the forward fuselage of an SR-71, and being roughly the size of an F-16. It was speculated that the aircraft was a drone that had "escaped".
If anyone has any more information on this aircraft, I would greatly appreciate if you send me it.
