2 of 7 crew members and 12 of the 101 passengers on board lost their lives.
The flight was being performed on a Boeing 727, registration #NA473DL, which was the 992nd. Boeing 727 to be delivered. It had been delivered in 1973.
Two facts were primarily blamed for the tragedy of flight 1411: The crew had not ensured that the wing's flaps were properly positioned for take-off, and the plane's unprepared take-off horn was not functioning. As a result, the plane struck a nearby object immediately after taking off, causing the accident.
