Individuals have reported seeing unusual triangle-shaped aircraft flying over the United States. A high number of these sightings have been around Area 51. Some individuals believe that these sightings provide evidence that the US government is flying captured extra terrestrial craft. Other researchers believe that these individuals are merely witnessing tests of the latest top secret US aircraft.

The United States government has allegedly produced a hypersonic stealth aircraft that can fly Mach 6 named Aurora. The mission of the Aurora aircraft is to provide aerial reconnaissance anywhere in the world. The Aurora was built to replace the aging fleet of SR-71aircraft that were taken out of service in 1990. The code name for this project is 'Senior Citizen' and the name 'Aurora' came from a 1985 Pentagon Budget report that listed the secret Aurora Project by mistake. The project allegedly started in 1987 and its first flight occurred in 1989. The plane is rumoured to have been developed by the Lockheed Martin Skunk Works who are famous for creating the U-2, F-104, SR-71, and F-117A and the F-22.

Many individuals believe it would be easy to mistake the Aurora aircraft for a UFO due to its' alleged shape and flight performance. Unfortunately, due to the secretive nature surrounding the operations of Area 51 individuals are unable to obtain physical proof that these strange craft are secret test planes or extra terrestrial craft.
