At last the Pentagon has acknowledged funding a secret multi-million-dollar programme to investigate sightings of Unidentified Flying Objects (UFO).

"The advanced aviation threat identification program ended in the 2012 timeframe. It was determined there were other, higher priority issues that merited funding," ABC News on December 18 reports quoting the Pentagon.

Many alleged sightings were investigated by the secret 22 million-dollar UFO unit run by the Pentagon, the headquarters of the United States Department of Defense, located in Arlington County, Virginia, the ABC News said in a video report.

"its moving around, left, right, forward, back, the radar nearly starts getting jammed, all of a sudden it takes off," said Cmdr David Fravor (retd) of US Navy who witnessed an alleged UFO during while piloting an FA 18 in a training mission on a day in 2004.
