Design and development

The Prue 215 is an all-metal design with a short 40 ft (12.2 m) wing with a relatively high aspect ratio of 20:1. The wing uses a NACA 23012 airfoil at the wing root, becoming a NACA 8318 at the wing tip. Airfoil-shaped flaps are mounted below and behind the wing for glidepath control. The aircraft uses a retractable monowheel landing gear.[1][2][3]

Three Prue 215s were built, all as amateur-builts from plans. The initial one was Prue's prototype. The second one was built by Ed Minghelli and later owned by Max Dreher, who mounted a jet engine on it. The second and third built are designated 215A.[2][4][5]

Operational history

The second Prue 215 built was flown to second place in the 1958 US Nationals by Harold Hutchinson.[1][2]

Only one Prue 215 remains listed on the Federal Aviation Administration registry.[4]

gollark: Interesting opinion.
gollark: As long as they don't deliberately cripple other ways which may sometimes be better.]
gollark: Sure, I guess.
gollark: If we assume that the badness of things is normally distributed, then adding additional things increases the chance of a good thing being available.
gollark: Eh, maybe? It depends on whether the "one way" they pick turns out to actually be good or not.
