WITH lightning speed, the second of the University of Michigan rocket firings is shown within a fraction of a second timing. The projectile is shown proceeding in a northeasterly direction between Manitou Island and Keweenaw County’s first westerly habitation, Copper Harbor. No person approached the site closer than 50 feet. The camera here is behind one of the snowmobiles used to carry the firing party to the site. Lake Superior was calm with only a gentle lapping of the waves against the shoreline of rocks, pebbles and stray driftwood. Dr. Harold Allen, party director, said this rocket would go up 22,000 feet and move horizontally about 9,000 feet. (Additonal photos on Page 14) (Gagnon of the Gazette)
