Even without purpose-made mods like available thermal cameras, DJI drones helped minimize damage to Notre Dame. According to The Verge,
Fire brigade spokesman Gabriel Plus told local media that the drones were instrumental in saving the cathedral’s structure. “The drones allowed us to correctly use what we had at our disposal,” Plus said in comments translated from French. Firefighters also relied on the Mavic Pro’s visible light camera and optical and electronic zoom…
“The mission was delicate and they intelligently called for the Parisian Police Drone Unit cell, which is a dedicated team of professional drone pilots ready to intervene in critical missions,” the spokesperson added. The drones were borrowed from France’s culture and interior ministries, as firefighters still don’t have their own drones.
