In the aeronautical world, one of the biggest risks is when a plane collides with a bird (of a certain size, naturally), which can happen when taking off or landing, since in certain cases said collision can cause one of the engines of the plane to breakdown and stop working.
And as a friend who was an aeronautical engineer told me a long time ago: large planes without engines glide like bricks.
I have located evidence of an aviation plane that is subjected to the crash test with a bird, and the truth is that the video is shocking. It can be seen at the following link: https://youtu.be/lgspIiTFWIk
The most famous case was that of the plane that had to land in water in the Hudson River (New York) in 2009. And fortunately without victims.

When planes fly high there is little risk of colliding with birds, and the problem increases when they are close to the ground, during landing and takeoff.
All large airports have systems to “scare” birds away from the landing strips and their surroundings, from the use of birds of prey to other more sophisticated strategies.
Statistical data tells us that since 1988 there have been 262 serious strikes with birds, and 250 airplanes have been destroyed, which are very few if we take into account the tens of thousands of airplanes that fly every day.
In general, you should not be afraid of flying, since today it is one of the safest transportation systems, but there is always some risk.
