Florida Air Museum is located at Sun 'n Fun in Lakeland, not very far from Fantasy of Flight. It seems smaller than Fantasy of Flight, but nevertheless has some interesting planes.

Convair F2Y-1 Sea Dart - A supersonic seaplane from 1953 with hydro-skis. One of the 4 surviving prototypes.
Pratt and Whitney R-4360 - A 28 piston engine, 8 of which were used in Hughes H-4 Hercules. This cutout with a press of a button brings the inner parts of the engine to life. Very educational.
Bell P-63 Kingcobra - An American WWII fighter used mainly by the Soviet Union. See the markings?
Hawker Tempest II - A British figher plane from WWII. Here with French "Cross of Lorraine" markings.
Lockheed XFV-1 - This is the ONLY flying prototype of the Lockheed XFV experimental tailsitter fighter from 1953.
BD-5B - The Jet version of that plane is the smallest Jet plane in the world.
