Drone 3D Maps Volcano

“I have flown in some really crazy places,” says Jardine, recalling his past work in caves, around big waves, and underneath the Sydney bridge. But the vast scale, whirling winds, corrosive fumes, and intense temperatures of Marum Crater presented new challenges. The previous day, Jardine had taken the plunge into the crater itself in order to get footage of the lava lake at closer range than would be practical for human participants. “The bottom of Marum Crater was definitely the most insane place to fly a copter, especially a plastic one,” he says. “The hardest part of flying was the hot air rushing out and cold air getting pulled into the lake. The machine would surge forwards and I would pull back on the stick. Then the hot air would blow in my face 10 times hotter than a hairdryer, and I could see the copter blasting back at me, so I’d push forwards on the stick, and so on. It was like playing tug-of-war with a drunk drone.”
