So much wreckage rained over a wide area, as the plane came apart in the air, that it was first believed that two planes had collided. However, the Federal Aviation Agency and the State Police said that all the pieces they could find were from one plane — Northwest's Lockheed Electra Flight 710. A wing and two engines of the wrecked turboprop were found about five miles (8 km) from the place where the plane's fuselage hit. Almost nothing was left of the craft. Hours after the crash, a column of blue-gray smoke still rose from the crater, about deep and wide.
