Not ZK, but still of interest....

Outside at Ardmore today, 27Jan, undergoing engine runs was this magnificant De Havilland DH89 Rapide, G-ADDD.

Thanks to Anon, we now know the original G-ADDD was owned by the Prince of Wales from mid 1935 and absorbed into the newly-created Kings Flight in July 1936. It was replaced by an Airspeed Envoy in 1937 and bought by Western Airways in Nov 1938 before moving to the RAF.

This particular airframe is c/n 6782 ex NR683, G-AHXW and N683DH restored as "G-ADDD".
