Content: Terrain is marked by the sea level, so some terrain may be much higher above sea level than the runway/airstrip. That’s why planes ‘climb’ to an appropriate altitude to stay away from any sort of ground structures. It is forbidden to fly below 1,000 feet for commercial airplanes by most aviation authorities around the world unless there is an emergency. This is for safety and environmental reasons, like noise. If you have been close to an airport before, you know that commercial airplanes are very loud and noisy. However, at around 35,000 meters, airplanes lie on the sweet border between the troposphere and stratosphere. This region is almost free of birds, insects and microbes, so the chances of a birdstrike up there is zero. Miracle on the Hudson
There have been many instances of bird strikes on airplanes, but the one that got the most attention was the case of US Airways Flight 1549. Back on January 15, 2009, an airplane (Airbus 320) was struck by a flock of birds that caused both of the plane’s engines to fail. Fearing that the plane wouldn’t be able to make it to the airport or a safe place nearby, the pilot had to allow the plane to descend into the Hudson River and sink there.
