January 15, 2009, A flight from Canada were transiting the New York airspace en route to South Carolina. The Victor formation of 20 plus were Southbound holding 2800 feet. Weather at 2:51 p.m. was 10 miles with broken clouds at 3,700, winds 8 knots from 290°.
At 3:27:11, in clear visual conditions, an unknown aircraft struck the formation from the 5 o’clock position at an altitude of 2,818 feet approximately 4.5 miles north-northwest of LaGuardia.
On January 21, the NTSB found evidence of damage in the right engine along with organic debris including a feather. The remains were later identified by DNA testing to be Canada geese.
On May 4, 2010 the NTSB issued its final report concluding that the crew of UA Flight 1549, under the command of Chesley B. Sullenberger, and First officer Jeffrey B. Skiles, failed to maintain visual separation with the Southbound flight of geese, whom at the time were in VMC and clear of cloud.
The case was brought before an aviation accident review board, but in the end, the crew, although clearly, and directly responsible for the collision, we're free to fly again.
