An article in the New York Times overviews a drone damage survey of the Fuentidueña apse, which dates to the 12th century. "The drone survey will let Ms. Kargère compare the drone photographs to images taken in the 1990s. The drone made it easier to see into high-up crevices and peer at the figures on the corbels, the brackets just under the roofline. Sunny weather helped, too. The survey in the 1990s was done in late winter. 'Everyone was freezing,' Barbara Bridgers, the head of imaging for the Met, recalled. This time around, the drone was sitting in the cobblestone driveway behind the apse, not far from a tent that had been set up as Mission Control. 'It’s like you’re walking into a James Bond set,' one Met official said, looking at the paraphernalia — a laptop, a portable monitor and extra batteries for the drone and the camera. A fully charged battery keeps the drone flying for about 20 minutes."
