Aurora

Aurora is an alleged American reconnaissance aircraft. Its existence is unconfirmed. In August of 1989, a former Royal Observer Corps member working on a North Sea gas rig spotted a matte-black aircraft refuelling from a KC-135. It is possible this was a prototype of the cancelled A-12 Avenger II, or a similar alleged reconnaissance aircraft known as the TR-3A Black Manta.

In 2014, the Daily Mail reported on mysterious booms heard across the UK and New York. The leading theory regarding their origin is that they were created by an aircraft travelling at supersonic or hypersonic speeds above the Atlantic. This led conspiracy theorists to attribute the booms to Aurora.
