Aircraft American Airlines Flight 1572 was a regularly scheduled passenger flight from O'Hare International Airport in Chicago, Illinois to Bradley International Airport near Hartford, Connecticut. On November 12, 1995, Flight 1572 was operated using a McDonnell Douglas MD-83, a twin-engine, narrow-body jet airliner (registration N566AA). The aircraft was equipped with two Pratt & Whitney JT8D-219 engines. The MD-83 had accumulated a total of 27,628 flight hours at the time of the accident. Flight history Flight 1572 was scheduled to depart from O'Hare at 21:25 Eastern Standard Time. Because of bad weather and delayed connecting passengers, however, the flight was delayed and did not depart until 23:05. While en route to Hartford, the flight crew, Captain Kenneth Lee (39), and First Officer John Richards (38), received an ACARS printout for the weather at Hartford. It noted an altimeter setting (reference atmospheric pressure) of , adding that pressure was falling rapidly in the area. The flight cruised uneventfully from Chicago to Hartford, other than changing from to to avoid reported turbulence. While on descent into Hartford, the pilots received a weather update at 00:30 that included a warning of wind shear and severe thunderstorms at Bradley.

At 00:34, the first officer checked the Automatic Terminal Information Service (ATIS) automated weather broadcast for Hartford, and noted to the captain that the most recent ATIS broadcast was about 90 minutes old. For reasons unknown, the first officer entered on the altimeter causing it to read approximately high. The captain checked the aircraft's weather radar before beginning the non-precision VOR approach to runway 15. Seeing no convective cells on the aircraft's path, he then turned the radar off. At 00:49, while Flight 1572 was beginning its final approach, the crew was advised that the control tower was closing temporarily due to severe weather buckling a window inside the cab. The tower supervisor remained behind to assist the flight. The captain noticed the autopilot was having difficulty maintaining
