Why do birds hit planes?

Sometimes the collision may not be an accident.

Now the situation of birds colliding with planes is relatively reduced, because the relevant departments have taken precautions against such situations. In the past, we may have heard of many accidents caused by birds hitting planes, as if planes could hit them as long as they hit birds. What caused the birds to collide head-on without avoiding the plane?

Bird strikes are very dangerous for airplanes. It usually happens during take-off or landing, and of course it will also make these birds in the wrong place at the wrong time die tragically. The impact of birds on the cab and engine has led to numerous crash landing and plane crashes. In March 2009, an Airbus A320 of United Airlines crashed into a flock of geese, so the plane had to land in the Hudson River. Fortunately, the pilot was highly skilled, and 155 no passengers or staff were killed. But everyone can't be so lucky. 1960 5438+00 In June, a Boston passenger plane was hit by a flock of starlings, and the plane crashed, killing 62 people. In recent years, photographers have been able to capture the moment when the engine of a big plane swallows birds.

In terms of small aircraft, another famous event happened in 2009 at the Red Bull Aerobatic World Tour in San Diego. A poor brown pelican accidentally flew straight to the front of Hannas Archie's plane, which was smashed in an instant. Of course, there are many similar incidents. The earliest photo of a bird hitting a plane was also found in The New York Times's photo archives. Photographed in 19 16 10, it shows a still alive raptor hanging on the metal cable of a French military compound wing aircraft.

It is very important for the airport to do a good job of driving away birds.

Sometimes birds don't hit planes for no reason. In some cases, birds will deliberately attack planes. Almost all of these cases involved eagles (although western Western jackdaw, ravens, falcons and macaws were also included in the attackers). In some cases, these birds seem to be defending their nests, and even once, the attacker launched a counterattack after being hit by a plane.

1960 In February, a single-engine "Pioneer" of the Royal Air Force was hit by a seahawk over the Malay Peninsula. The pilot reported that the seahawk was attacked with its claws. It hit the windshield and died, and then it stayed in the cab. According to Ryan's book, H.T. Wilkins revealed that France tried to train six eagles to attack enemy planes in World War I. These eagles first needed to adapt to the noise of propellers and artillery fire, and then they would associate the aircraft with food rewards in training. But in any case, this plan has never been realized.

Although birds are small for airplanes, the harm caused by the collision between birds and airplanes in high-speed flight is very serious. Therefore, the airport will arrange some staff to disperse birds, which is actually a relatively important job. Because many times planes and birds may not collide accidentally, and some birds also have a certain sense of territory and will attack planes. If you don't drive away, it is likely to be dangerous.
