This is a hyperlapse of a sunrise above the clouds during a high altitude climb and descent. The unknown pilot posts this video with a warning. Do not attempt a hyperlapse at high altitude when the battery can't sustain the flight time needed for the making of the hyperlapse. If needed cancel the hyperlapse when the battery reaches a point of literally no return. Cancel the hyperlapse and land ASAP. This drone, an Air2S, suffered the fate of Icarus. It went up, saw the sun, and fell to it's demise. The pilot, knowing the inevitable, moved the aircraft over an empty grassy field. He/She knew the drone would eventually freefall. The empty field was chosen for the safety of people, property and easy drone retrieval. Luckily, Care Refresh was still active.
