Washington: Dr. Steven Greer, a well-known American scientist who researches flying saucers (UFOs) from other planets, has claimed that at least 119 extraterrestrial spaceships have crashed on Earth.
Dr. Steven Greer, 67, said the U.S. government collected debris from various locations and used it to build advanced energy systems that have not yet been brought to the public.
Dr. Stevens said that over the past 30 years he has obtained US government documents about UFOs and testimony from 700 military and intelligence officials.
The doctor plans to go public with his research files at a press conference in the US capital on June 12. He said that he would present definitive evidence of secret black budget projects related to unidentified flying saucers.
