It was clearly all caused by the still travelling "magic bullet" that caught President Kennedy a wallop and then turned several times in mid air before going back and swiping a bit of senator .... It came from Area 51 in 1948, has been seen many times and mistaken for flying saucers, before the Dallas episode in 1963, and turning up in Paris that fateful night. It briefly half materialises on our stairs, causing the cat to chase madly around for 20 minutes a month.
