Private Chinese Rocket Accidentally Launches During Test.

A private Chinese rocket took an unscheduled flight over the weekend.

The Beijing-based company Space Pioneer conducted a “static fire” test with the first stage of its new Tianlong-3 rocket on Sunday (June 30) in Gongyi, a city of about 800,000 people in the central Chinese province of Henan.

Space Pioneer briefly ignited the stage’s engines while the vehicle remained anchored to the launch pad. That’s how it was supposed to work, anyway. But the anchoring mechanism failed on Sunday, and the rocket lifted off on a dramatic and frightening surprise mission.
