Astride the nose of Gemini 11, Gordon moves forward to attach a 100-foot line from the Agena, directly in front of him, to the manned vehicle. 

"I’m riding it like a cowboy,” he said to Command Pilot Pete Conrad. This photograph was taken with a movie camera mounted over the open hatch of the spacecraft.
