Governments have spent years covering up UFO sightings, a leading scientist has claimed.
A leading scientist has claimed that governments are covering up evidence of UFOs
Nobel Prize nominee Professor Garry Nolan says that he "knows" that the authorities have been hiding knowledge of extraterrestrials for decades but feels that new public hearings will blow alien secrets wide open.
Professor Nolan, an immunologist at Stanford University School of Medicine, said: "I've spoken to people who are about to come out and whistle-blow on it.
"There's been an active cover-up."
Proposed new laws that are awaiting approval from US Congress could pave the way for open hearings into UFO sightings, where witnesses will have the chance to give evidence under oath about the flying spacecraft.
The government body has even demanded a list of non-disclosure agreements linked with secret UFO programmes.
Nolan said: "Why is that interesting? It's not the NDAs themselves.
"It's the people who signed the NDAs because that then is the paper trail to the individuals and the programmes in which they're associated."
