Years ago when I worked 747 Majors for the world's favourite one of my colleagues was sent on a Concorde course three years before he retired. We asked him what was his earliest involvement with aviation, thinking it would be Airspeed Ambassadors or something of that nature. In fact, as a Boy Scout he had helped on the mooring ropes during a visit to Croydon by the Hindenberg. That's quite a span - from Zeppelins to SSTs via Argonauts, Sratocruisers, 707s and Jumbos. Aviation has made some truly amazing advances in its short history.
