PHOTO SHOOT: Day 5—Wallenda Grand Canyon Cable Installation: Cable Pull, Lockdown & Tensioning



For the first half of day five, crews split up between the two venues for pulling the cable across the canyon.  Later that afternoon all hands were on deck at the mainland site for final cable securing measures as it was drawn to an event-ready tension of 60,000 pounds.  I flew over with the island crew in the morning to capture happenings from that perspective.
