I know, not amateur radio related. But I thought I'd share a couple videos that are quite amazing and spectacular, the first two taken using DJI Mavic Pro 3's.The first video shows the entire route up to the top of Everest (at faster than normal speed of course). The Khumbu Icefall in the first segment of the first video makes one wonder how anyone can get through that area alive.Didn't know a quadcopter could fly at these altitudes given the low air density. High rotor rpm plus lots of excess thrust-to-weight at sea level I guess. The BIG drone in the 3rd video is really impressive.Best viewed on a large monitor or smart TV. For some reason I could not get these to run using the Firefox browser. I used Edge. Also OK on Android but the small screen size detracts.EnjoyN3AERoute Up EverestOverflight of EverestGarbage Trip Using Bigger Drone
