Ukraine Sounds Alarm on Chinese Drones, Opening Skies to U.S. Startups

Hovering in the sky above Ukraine are hundreds of small drones from U.S. startups, searching for survivors in war-pummeled cities and Russian hide-outs in the scarred landscape.

Those startups, including Seattle-based BRINC Drones Inc. and Silicon Valley’s Skydio Inc., are rushing to fill a gap in Ukraine after government officials called out products supplied by Chinese company SZ DJI Technology Co., the world’s largest commercial drone maker, as a security risk for Ukraine’s military and civilians.
