Vuelopedia is a work in progress: it currently holds about 30% of the information we expect to have by the third quarter of 2027. Although we use only official, highly reliable sources, some aircraft data and history may still contain errors or inaccuracies. We work hard to clear every anomaly from the records using specialized verification tools.

What happened

On 11 September 2001, after the attacks with hijacked aircraft on the Twin Towers in New York and the Pentagon, the FAA ordered — for the first time in history — the complete closure of United States airspace (the SCATANA plan): all civil aviation was told to land immediately, and by midday the American sky was clear. Around 240 international flights bound for the United States were diverted to Canada — Operation Yellow Ribbon, with more than 30,000 passengers. Airspace reopened gradually from 13 September, by then under new security measures. Source: the FAA (United States).

Accident Southern Tip of Greenland

On May 25, 2010, the Boeing 777 aircraft (registration N794UA), operated by United Airlines, was involved in an accident Southern Tip of Greenland (Denmark), leaving 2 injured. Source: the NTSB (United States).

What happened

The flight met clear-air turbulence near the southern tip of Greenland. The weather documentation provided by the company's dispatch included the relevant SIGMETs for the route and no published information was missing that could have warned the crew of the encounter. Wind analysis indicated that the aircraft first passed through a downdraught of the order of 13 feet per second and, abruptly afterwards, an updraught of about 24 feet per second. Simulations confirmed that the aircraft responded as expected to that wind profile and that the elevator input applied by the autopilot reduced the magnitude of the excursion. Study of the atmosphere and GOES-3 satellite imagery revealed wave instability over the ice cap, capable of generating vertical winds of up to 20 feet per second, conducive to severe turbulence.

Airworthiness directive

On February 23, 2021, the Boeing 777 aircraft (registration N794UA), was subject to an airworthiness directive due to a fatigue failure of a fan blade on the Pratt & Whitney PW4000 engine, prompting repetitive inspections and structural reinforcement of the inlet. Source: la FAA.
