Within minutes after takeoff, the pilot of the Cessna T210 began dealing for the second time that day with an in-flight mechanical problem. According to published reports, the pilot a short time earlier had diverted to Clarion County Airport in northwestern Pennsylvania to investigate an oil pressure issue during his flight from Westchester County Airport in New York back to his home in Akron, Ohio. He reportedly took off again a few minutes later into the dusk of November 24, heading across the dark rural landscape, climbing only to 4,000 feet. Nineteen minutes later and after reporting mechanical issues to air traffic control, he crashed just 1.5 miles short of the Grove City Airport. The pilot died at the scene. His passenger died a few days later in the hospital from burns and inhalation injuries.
