Instead of planes, why not used a tethered balloon with a 360 camera, and direct fiberoptic cable to the ground. Curious how high a balloon like this could go up before it exceeded the weight and strength limits of the filament line.
Okay great thanks, so a consumer 1200mm lens can zoom upto 8 miles. But I guess under 45 degree angle, you would only get about 4500 feet horizontal range
