The three most prominent incidents:
(*) Eastern Flight 401, 1972--The L-1011-1 flight from JFK to MIA crashed in the Florida Everglades after the captain accidentally disengaged the autopilot without realizing it at a low altitude. The crew was busy troubleshooting the nose gear light, which had not illuminated when they selected gear down and locked. With no visual references over the darkened swamp, they decended down to treetop level before anyone realized what was going on. By that time, it was too late. Crew Error, 76 survivors out of 175.
(*) Saudia Flight 163, 1980--The L-1011-1 flight from Riyadh to Jeddah caught fire shortly after takeoff after a small stove in the baggage compartment ignited. The fire spread quickly, and the aircraft returned to Riyadh, where it made a safe landing. However, the aircraft continued to taxi along the runway slowly after arrival, indicating that the crew perhaps did not understand the severity of the fire. Additionally, the emergency doors could not be opened due to an electrical malfunction. By the time the doors could be opened, it was too late--everyone aboard the completely full aircraft had died of smoke inhalation. Inflight Fire, Crew Error, No survivors out of 301.
(*) Delta Flight 191, 1985--The L-1011-1 flight from Ft. Lauderdale to Dallas/Ft. Worth (continuing on to Los Angeles) was on landing, decending down through a fierce Texas rain storm. As they approached the runway threshhold, the aircraft entered a severe microburst, causing the aircraft's airspeed to characteristically increase. Noting the spike, the crew then knew they were caught in windshear, and the engines were spooled up, and the aircraft pitched upward. But it was too late--the aircraft slammed down in a field short of the runway and raced along, crossing a highway and obliterating a car on the shoulder. The man inside was on his way home to catch a phone call from his wife on his birthday, was killed instantly. The aircraft bounced into the air again, then impacted on the airport property, thundering into two water towers and killing most of the passengers in the front portion of the aircraft. However, the water is credited with helping to extinguish the flames more quickly, saving those in the rear of the aircraft. Windshear, 29 survivors out of 163.
