Remarkably so. A five ship flyby is happening this weekend up Southampton water to overfly the original Supermarine works at Wollaston, where RJ Mitchell and his team designed the aircraft and onward to Eastleigh, now Southampton International, where K5054, the prototype, made its first flight.
AND still more are being made airworthy, hardly seems possible!! The latest will be a Seafire, the first to be renovated to airworthy condition.
