L. R. Aalund Managing Editor-Technology The third phase in the world's most sophisticated deep drilling project ended this summer with the borehole at a depth of 3,003 m or 9,852 ft. The scientific probe into the lithosphere near the German/Czechoslovakian border in Bavaria is on schedule and now well into the fourth phase that will carry it to a depth of 6,000 m (i 9,684 ft). At mid-September, the hole depth was 4,250 m. The final objective is a depth of 10-12 km or some 33,000-40,000 ft.
