Principal electronics technician David Havens turns the wheel which adjusts vertical angle on the new satellite weather antenna, state of the art antenna for its time, installed aboard D/V Glomar Challenger (ship) during the port call at Agana, Guam, between Legs 59 and 60 of the Deep Sea Drilling Project.
