There have been several reputable reports of triangular shaped UFOs, some with silent hovering characteristics, and others capable of extraordinary speeds. How much the government is sinking in advanced technologies are not only secret, but they have little if any oversight from our elected officials.
Every so often, a curtain of secrecy is lifted slightly, such was the case involving the Aurora project:
Budget and Financial DataThe first suggestion that these studies might be translated into operational hardware appeared in the Fiscal Year 1986 procurement program document, colloquially known as the P-1, dated 4 February 1985. A line item in this document, labeled "Aurora," was slated to receive $80 million in 1986, and over $2.2 billion in 1987.<73> Since this line item appeared next to the line funding the TR-1 reconnaissance aircraft, it stirred up a hornet's nest of conjecture that a secret aircraft was being developed to replace the aging SR-71.
The Air Force quickly denied the existence of a secret program, and said the "Aurora" budget line was simply one site for B-2 bomber funds when that program was highly classified.<74> One Air Force official commented, "I wish I could say it is (an SR-71 follow-on), because we'd love to have it. But it's just accounting, I'm afraid."<75>
Others disagreed. One journal reported that "the general consensus now is that the item did not refer to the B-2 bomber but to another effort."<76> Other analysts placed the SR-71 follow-on at both Edwards Air Force Base and Nellis Air Range.<77>
Other publications saw a more complicated, more expansive black world. These periodicals posited that Aurora was one of several code names "nested within other code names, all referring to a class of aircraft designed for multiple missions."<78>
However, the discussions of the Aurora budget line item overlook one very crucial fact:
No money was ever appropriated for Aurora!
In the February 1985 submission of the FY 1986 budget, the Aurora line item projected a request of over $2 billion in the FY 1987 budget. But one year later, when the FY 1987 budget was submitted, the Aurora line item had vanished as mysteriously as it had first appeared. Indeed, FY 1987 request for the overall Air Force aircraft procurement account was several billion dollars less than had be projected in 1985, and there were no line items in the FY 1987 request that could have been used to conceal a request for funding for Aurora.
