Shifting Winds Force Helium Balloon to Land

A helium balloon on a test flight with a crew of three who plan to study the ozone layer made an unscheduled landing in a remote spot after the wind shifted, a spokeswoman for the Earthwinds project said Monday.

The crew included the Soviet Union’s chief of cosmonaut training and the inventor of the ultralight aircraft. No one was injured in the landing about nine miles south of here, she said.
