The NTSB's narrative final · quoted from the NTSB record
While cruising during a scheduled domestic flight, the captain began experiencing chest pain. The flight diverted to Denver, where the first officer made an uneventful landing and the captain taxied the aircraft to the gate (the L-1011 was not equipped with nose wheel steering on the first officer's side). The captain was transported to a medical facility. According to emergency room records, the captain had no history of cardiovascular disease. He reported he had been experiencing intermittent retrosternal chest pain since the previous day which was becoming more continuous with radiation to his left jaw and left arm. The clinical impression of the attending physician was chest pain with possible unstable angina, although his electrocardiogram (EKG) was normal.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number FTW96IA240.
