Apple`s Campus 2 is under construction and it seems will take sometime yet to finish the building also known as "Spaceship" because of its roundness similar to a flying saucer UFO.
The anonymous pilot, reports 9to5Mac, took pictures and shot video of the work in progress, which cannot be clearly seen from the ground.

The quad copter remained under 400 feet as per FAA Advisory Circular 91-57 for remote controlled airplanes and helicopters and the helicopter did not encroach into any airport no-fly zones. No people were present and no equipment was operating at the construction site at the time of filming.
