500th VLA Antenna Move

Start Date:1984-11-05 Location:VLA Site, NM	Creator:Records of the NRAO Series:Photographs Series Unit:VLA Unit Type:Still Image Subject:Instruments--Very Large Array (VLA)	Description:The 500th move of a VLA antenna took place on 5 November 1984. The cartoon, drawn by Paul Harden, commemorates the milestone event and the dedication of the transporter crews. The crews braved scorching sun and blowing snow (and probably blowing sand), as well as wobbling tracks (and sometimes broken ones as the cartoon suggests) to move antennas to a new location. The transporters at that time were named Hein's Trein and CamTrak, honoring long-time NRAO staff members Hein Hvatum and Cam Wade. Photograph of original cartoon drawn by Paul Harden. [show more]
