The last remaining F-20 Tigershark on display at the California Science Center in Los Angeles, with a T-38 Talon above. The T-38 is the original design that led to the F-20, and the similarities are evident in this photo. The changes made for the F-20 include the much larger single engine, larger elevators to provide better pitch response, expanded forward fuselage holding upgraded avionics, and the leading edge extensions on the wing to improve overall maneuverability.
