Polish military officer dies after fall during climb of Mount Hood in Oregon According to its website, Insitu instructors have trained more than 2,000 drone operators and maintenance technicians from across the world. Poland, an Insitu customer for several years, has plans to expand its use of unmanned aerial vehicles. The novice climber used an off day to go up the mountain Sunday, and was reported missing by a room-mate the next morning. Crews found his vehicle at a trailhead, but a daylong search of two routes that start at that point failed to find him. Kinasiewicz's rank and survivor information were not immediately available. Websites in Polish say he was a warrant officer and had a background in photography. His work is displayed on a Facebook page dedicated to combat photography. Thousands of people climb the 11,239-foot (3,425-meter) peak each year, mostly in the spring. Summer climbing is more dangerous because warmer temperatures melt the ice and loosen rocks. A snowboarder from Colorado died on the mountain earlier this month when an ice tunnel collapsed. In July, searchers found the body of an Oregon dentist who suffered a fatal fall during a solo climb.
