The unusual thing about this particular tragedy is the existence of the drone footage. If you search in the internet, there exists a footage of a flyover around Everest, but at those altitudes it is really uncommon. The technology is very new and almost NASA-grade: Ingenuity was a successful proof of concept, DJI is now showing modified commercial drones. It looks like those currently available drones won’t be able to get there any meaningful payload, so we can only watch people dying in high resolution, but not save them.
