On December 29, 2024, a Boeing 737-800 traveling from Bangkok to Muan, South Korea, crashed during landing, killing 179 people and injuring 2 people, writes focus.it.
According to initial reconstructions, among the possible causes of the accident is the hypothesis of bird strike, i.e. a flock of birds colliding with one of the engines.
Collisions of this type have occurred since humans learned to fly, invading a space that was previously the exclusive domain of birds. They usually occur during takeoff or landing and therefore at or near airports.
According to the latest report on the subject, birds generally fly below 500 feet (152 meters) when not actively migrating. The phenomenon is increasing mainly due to the massive increase in air traffic, but also due to the growth of some bird populations.
Airplanes are designed to withstand this type of collision, however when a bird and an airplane collide, due to the high speeds and masses involved, the impact can cause significant damage, rendering the airplane unable to fly or in an emergency situation.
Just consider that a 5 kg bird hitting a landing plane at 240 km/h is equivalent to a half-ton weight dropped from a height of 3 meters.
Usually, however, it is the bird that has the worst luck: when it ends up sucked into an engine, it usually disintegrates and in many cases the pilots notice the accident after landing, when checking the engines.
However, it can happen – especially if you hit a bump – that part of the engine bends or becomes damaged, causing a loss of power and jeopardizing flight safety.
Fortunately, airplanes are designed to be able to land with just one engine.
