Nigeria Airways Flight 2120 (1991)
More than 200 people died on the Nigeria Airways Flight in 1991. This DC-8 crash prompted engineers to make some serious changes in tire safety procedures. The under-inflated tire caused this fatal crash, forcing a necessary look at the design of aircraft tires. Pilot error was also a part of this. A report on a fatal day said, “Before take-off, the lead mechanic of the Nigeria Airways Flight 2120 noticed two tires were below the minimum for flight dispatch and tried to inflate them – but no nitrogen gas was readily available. But despite this, the project manager, not willing to delay, gave the all-clear for take-off.” This pilot error, in addition to mechanical error, had a fatal result (Daily Star).
