Timeline
Routine departure morning at O’Hare
**1979-05-25** — American Airlines prepared Flight 191, a Los Angeles-bound DC-10, for departure from Chicago O’Hare International Airport. The airport’s normal traffic rhythm concealed the maintenance vulnerabilities already present in the aircraft’s left engine-pylon assembly.
Improper maintenance history comes due
**1979-05-25** — The aircraft’s left engine had been removed and reinstalled using a procedure later judged improper by investigators. That work left the pylon assembly vulnerable to separation during the takeoff roll.
Takeoff roll begins
**1979-05-25T14:00** — Flight 191 accelerated on Runway 32R at O’Hare. At the threshold of liftoff, the aircraft still appeared to be following a normal departure profile.
Engine and pylon separate
**1979-05-25T14:00** — The left engine and pylon detached from the wing during the takeoff roll, striking the wing and damaging hydraulic systems and leading-edge slats. The failure created an immediate asymmetric loss of lift and control.
Crash north of the airport
**1979-05-25T14:00** — The DC-10 climbed briefly, banked left, stalled, and struck the ground near Des Plaines, Illinois. The impact and ensuing fire destroyed the aircraft.
Emergency response mobilized
**1979-05-25** — Airport fire crews, local fire departments, police, and paramedics moved toward the wreckage as smoke rose from the crash site. Rescue efforts were hampered by fire, debris, and the scale of the break-up.
Survivors and casualty accounting
**1979-05-25** — Only two people aboard initially survived, and one later died of injuries, leaving Laurence Griffin as the sole known survivor from the aircraft. The accident ultimately claimed 273 lives, including two people on the ground.
Federal investigation begins
**1979-05-26** — The National Transportation Safety Board opened a formal inquiry into the accident. Investigators began documenting wreckage distribution, maintenance history, and witness accounts.
NTSB issues final findings
**1979-12** — The board concluded that improper maintenance and the resulting engine-pylon separation caused the wing damage and loss of control. The finding established the disaster as a preventable maintenance-induced crash.
Maintenance and inspection practices tightened
**1980** — Regulatory and airline procedures were revised in response to the crash, including greater scrutiny of engine-pylon work on DC-10 aircraft. The disaster became a major case study in maintenance oversight.
Public memorialization begins
**1979-06** — Families, airline workers, and the Chicago community began the work of remembrance as the scale of the loss settled into public consciousness. The crash site entered aviation memory as a place of warning.
Deadliest U.S. aviation accident established
**1979-05-25** — As casualty accounting was completed, Flight 191 was confirmed as the deadliest aviation accident in U.S. history. That grim status fixed the event in national memory and aviation history.
