Pretty cool. Generally, drones for last mile front line resupply makes a lot of sense. I'm just wondering about the mobility challenges of charging points to keep drones going because bigger and more numerous drones will rapidly require more electricity.
Also, China recently used drones to haul 180 tonnes of construction gear up a mountain. https://www.scmp.com/news/china/politics/article/3319460/chi...
