Franklin PS-2 (XPS-2) Glider: This beefy-looking glider is a Franklin PS-2, a pair of which were operated by the NACA at Langley beginning in April 1936. The Navy only ordered half a dozen of these training gliders, which had a glide ratio of 15 feet forward for every foot down. The devices above the pilot's seat are venturi tubes, which gathered data for the instruments. Airfield lights are seen above the wing.
