The Purcell Sea Sprite was an experimental homebuilt glider aircraft.
It was intended to be operated by experienced pilots under 200 feet attached to a tow boat.
Created by Thomas H. Purcell Jr. of Raleigh, North Carolina, the aircraft weighed about 175 pounds and could be built from plans for about $400 (in 1975 dollars).
