The Apollo 15 Hand Controller From Al Worden

As Al Worden, the Apollo 15 Command Module Pilot, puts it in the signed COA included with this hand controller, which is mounted on wood: “…this control stick cover, NASA serial number MSC 991-0001.12, was the hand controller I used during the flight of Apollo 15. The function of the hand controller was to adjust the attitude of the spacecraft during flight. For instance it was critical to the maneuver designed to withdraw the Lunar Module from the S-IVB stage of the launch vehicle once leaving earth orbit. This maneuver involved 180 degree rotation of the Command and Service Module to align with the Lunar Module in storage. It was also essential for the alignment of the spacecraft in the proper direction for any thrusting maneuver. This controller was essential to the success of Apollo 15 and has been in my possession since the flight.” In near fine condition.  Sold for $72,556.
