Acquired Nov 84 and converted to 73AF ex N907CL Capitol Air and N4907C Capitol Air International both with which it was a 63CF. It was retired in Mar 2009. Interestingly (for me anyway), I had flown on it as N907CL twice: once from LAX to JFK in Dec 81 and the second time from BRU to JFK in Oct 83.
SS Canberra was carrying a number of passengers heading for Australia. 4th January 1963 a fire broke out and disabled the ship. This was one of a number of aircraft charted to fly passengers to their destination.
