00:00One of the reasons for the death of 179 people and the survival of two people in the Korean Air Force,
00:04according to the official statement, is the possibility of a bird strike.
00:07There is a video that shows that in the process of landing,
00:11the plane seems to collide with a group of birds.
00:13The engine on the right side is on fire and makes an explosion.
00:16And the most serious air crash in the history of South Korea,
00:19the black box is found, but it still takes time to interpret the information.
00:23There are many uncertainties about the real cause of the accident.
00:26But is a small bird really so powerful?
00:31Is the impact of a small sparrow really equivalent to a bomb?
00:35Let's take a look at this video.
00:37In fact, there are about 20,000 incidents of bird strikes in the world every year.
00:41The situation is big or small.
00:43Some incidents are also called aviation miracles.
00:46There is an airplane down in the Hudson River right off Manhattan.
00:50This shocking scene happened in 2009.
00:53At that time, the United States Air Force had a flight number 1549.
00:56Shortly after taking off from the New York airport,
00:58a group of Canadian Black Swans crashed into the plane,
01:01causing the two engines of the plane to fail.
01:04After confirming that no airport nearby could be reached,
01:07the captain was forced to decide to land the plane on the Hudson River.
01:12155 passengers on the plane were rescued.
01:16The captain's miracle made this incident known as the miracle on the Hudson River.
01:21It is also the most famous bird strike incident.
01:23Another bird strike incident happened in August 2019, 10 years later.
01:28The flight number 178 of the Russian Ural Airlines
01:31also had multiple bird strikes,
01:33causing the two engines of the plane to fail.
01:37The captain wisely chose to land the plane on a cornfield not far from the airport.
01:41In the end, 233 people on the plane were saved.
01:44After this incident, the captain was even called a hero by the Russian media.
01:48It's a pity that heroes are always there, but miracles don't happen often.
01:52In addition, the frequency of bird strikes is not considered low.
01:56According to the statistics of the Federal Aviation Administration of the United States,
01:59between 1990 and 2023,
02:01the U.S. Civil Aviation Bureau reported more than 280,000 bird strikes,
02:06of which only 18,000 in 2023.
02:09The data of the International Civil Aviation Organization also shows
02:11that there are more than 20,000 bird strikes every year,
02:15causing the cost of the plane's damage or flight delay to reach more than $100 billion.
02:21Bird strikes have become one of the most dangerous factors that threaten aviation safety.
02:25The International Aviation Association currently lists bird strikes as a class A aviation disaster.
02:30But you may be wondering,
02:32compared to a small bird and a plane,
02:35the size difference is so big.
02:37According to common sense, a plane collides with a bird.
02:39It should be a soft rock.
02:41Is it so harmful to the plane?
02:44This involves some physical knowledge.
02:46Although the speed of the bird is not fast,
02:48the speed of the plane is very fast.
02:50When the impact force is equivalent to the square of the weight and speed,
02:54a 100-gram sparrow collides with a 400-kilometer-per-hour plane,
02:58it can instantly produce a 2-ton impact force.
03:01A 7-kilometer-per-hour bird collides with a 960-kilometer-per-hour plane,
03:05which is as powerful as a bomb attack.
03:08Light damage to the plane, heavy damage to the plane.
03:12Which part of the plane is most likely to be hit by a bird?
03:15According to the statistics of the International Civil Aviation Organization,
03:17the answer is the position of the engine.
03:20The probability is up to 44%.
03:22If a bird is stuck in the engine,
03:24the engine will stop or fire.
03:27Then there are wings, windshield, radar, fuselage and landing gear.
03:31Once the impact force damages the structure of the plane,
03:34such as the windshield breaking,
03:36the pilot will be in danger if he is unable to drive due to strong wind.
03:39And the most common moment of a bird collision
03:42is when the plane takes off or approaches the landing site.
03:46Therefore, it is necessary to prevent the bird from causing a major accident.
03:49The psychological construction and training of the pilot,
03:51the work of the airport to drive away the birds,
03:54and the design of the aircraft to fight against birds are all very important.
03:58For example, some airports will use small gas explosions
04:02to imitate gunshots to prevent birds from hovering nearby.
04:05There will be no more plants that attract birds around.
04:09According to aviation experts,
04:10although bird collisions are very common,
04:12as long as the two engines of the plane are not damaged by the collision,
04:17the birds' eggs do not block the pilot's vision,
04:20which usually does not lead to a malignant accident.
04:23Therefore, many aviators in South Korea
04:25have the opinion that
04:27the cause of the collision was not caused by the single cause of the bird collision,
04:30but everything still needs to be fully investigated.
04:33Will this incident affect your mood for the next flight?
04:36Have you had the experience of a bird collision when you were on a plane?
04:40Welcome to share your opinion.
04:41If you like this video,
04:43don't forget to like and share.
04:45We wish you a safe and peaceful flight.
