http://www.telegraph.co.uk/news/newstopics/theroyalfamily/4359649/Queen-and-Prince-Philip-were-victims-of-Australian-assassination-attempt.htmlThe so-called Republican plot came to light when retired Detective Superintendent Cliff McHardy, 81, decided to break his silence in an interview in his local newspaper to try to clear-up one of the great unsolved mysteries of his long police career.
McHardy said that on April 29, 1970, the Queen and Duke were travelling by train to the farming town of Orange. When the train entered a winding cutting near the Blue Mountains town of Lithgow, two hours to the west of Sydney, it struck a large log wedged across the rails. Mr McHardy insists that it was an act of deliberate sabotage to force the train off the tracks.
