This is a short walkaround of the Convair YF2Y-1 Sea Dart Bu.135765 which is on static display at the Florida Air Museum, part of the Sun and Fun Complex located at the Lakeland Linder Regional Airport in Lakeland FL.

As the dawn of the jet age, the 1950s saw its share of strange aircraft. Some concepts evolved to ideas still in use today, but others were only the result of trial & error practices fed by huge military budgets. The Convair F2Y Sea Dart was one of these bad ideas.




The Convair F2Y Sea Dart was a unique American seaplane fighter aircraft that rode on twin hydro-skis for takeoff. A number of prototypes were tested from 1951 to 1957, but the model never entered production.
It
lifted off at about 120 knots and took one mile to achieve this in calm seas. Work on the F2Y-1 testint ran until 1957, when the project was was finally closed.

It holds the distinction of being the only seaplane to have exceeded the speed of sound, though.
