The reason I went to Horse Guards Parade on Friday was to see these 3 aircraft. The Sopwith Snipe, a Spitfire and a Typhoon Jet. Friday was the 98th anniversary of the foundation of the Royal Air Force. The same aircraft are on the RAF centenary Project logo.
The Sopwith Snipe and the Spitfire overlooking the Parade ground as the Changing of the Guard is taking place. Doubt I will ever see that happening again.
The Sopwith Snipe was a successor to the Sopwith Camel and was first used by the RAF in September 1918 until 1928. This one on display was built by the Vintage Aviator company in New Zealand in 2011/12. Many of the parts, including the engine, are original from the RAF Museum
The Typhoon Jet was a full sized replica and was assembled on the Parade ground. A real Typhoon Jet flew over Horse Guards Parade later that day. It can fly at a speed of 1,320 mph. but I imagine it didn't reach that speed as it flew over London.
