This is probably my best P51 filming so far. Enjoy this fantastic airplane and the sound from her engine. North American P51D Cavalier Mustang II SEBIL/N405HC of Biltema Airshow. Outstanding display by great pilot Pär Cederquist. What makes this Mustang really special though is that it is probably the only Cavalier F51D Mustang II conversion still flying today. The Cavalier Mustang project was the idea of newspaper publisher David Lindsay, who established Trans Florida Aviation in 1957, with the intention of refurbishing exmilitary P51s into civilian business aircraft.
