Richard Kolyer unfolds the drone and prepares it for flight around the modified C-141 Kuiper Airborne Observatory, (KAO) (NASA-714).

The drone follows an autonomously defined path around the modified C-141 Kuiper Airborne Observatory, (KAO) (NASA-714), on the N211 apron. The drone photographs the aircraft with a visible and infrared camera which are processed using a photogrammetry software package called Pix4D that converts them into a 3D model. Scanning the aircraft is the first phase of documenting the aircraft demolition as well as an opportunity to train pilots to operate the Pix4D software.
