Claims that the world's superpowers have recovered and studied non-human technology have lingered on the fringes for decades, but new revelations are pushing them back into the spotlight.

Paul Stonehill breaks down what the documents actually reveal and puts the claims into context by drawing on his decades of research into Russian and Soviet UFO history.
