“The biggest, raddest, longest, most technically difficult ski line on the planet

Mark Hasara on Instagram: "I thought it hard to believe at first but it did happen. A very smart and athletic mountain climber packed his drone all the way to the top of Mt Everest and launched it! He’s sitting on a peak a bit over 29,000 feet tall, an altitude airliners operate at. His drone recorded spectacular views of the peaks, the snow, valleys, and scenery around him or her. Satisfied with the results, the drone was recovered and brought down the mountain. #aviation #avgeek #pilot #pilotl
