San Francisco hosts country's 1st-ever large-scale drone, projection show

SAN FRANCISCO (KGO) -- There was quite a light show high in the sky above San Francisco Wednesday night.

The city hosted the country's first-ever large-scale drone and projection show.

There were more than 1,000 drones, synchronized to form several different images - and then paired with projections on the Ferry Building clock tower.

The show was put together by the company "GAMMA" to help promote SF Tech Week.
