F-106A 59-0130 cockpit as used during the NASA Eclipse Tow project. Dryden added a research instrumentation system to obtain airspeed, aircraft motion, tow rope tension, and tow rope angle measurements. Modifications to the QF-106 included shortening the nose pitot boom and addition of a tow rope attachment and release mechanism. The cockpit was modified to provide the pilot with a tow rope tension display and also the two (an electrical and a mechanical) tow rope releases. A video camera was installed near the aircraft's nose to provide the control room with a view of the tow rope during the flight.
