This is an almost 4-mile drone flight up the French alps piloted by Romano FPV starting from Chamonix (altitude: 3379-ft) to the peak of Aiguille du Midi (altitude: 12,605-ft). That’s an altitude gain of 9,226 feet, or 1.75-miles. Damn, I would probably have trouble breathing all the way up there. Full disclosure: I have trouble breathing everywhere because of my allergies. I take drugs, but they don’t work. “Drugs FOR allergy relief?” Well let’s not get nit-picky.
