Aerospace technology is so advanced, why are there so many plane crashes?

The reasons for the plane crash are complicated, mainly due to weather and aircraft mechanical failure.

Weather is one of the culprits of plane crashes. Bad weather is one of the main reasons for plane accidents. For example, on April 4, 1977, Southern Airlines Flight 242 suffered engine inhalation due to bad weather. Due to heavy hail, co-pilot Lyman decided to make an emergency landing on Highway 92 in Georgia. As a result, the plane exploded, killing 70 people and injuring 21 others. Nowadays, aircraft are equipped with advanced electronic equipment, such as satellite navigation systems, weather data systems, gyroscopes, etc., but the power of nature is terrifying, and aircraft are still very fragile in these harsh natural environments.

Once a mechanical failure occurs, the aircraft will be on the road to crash. Mechanical failure is also one of the main causes of aircraft crashes, such as engine failure, landing gear failure, etc. The manufacturing of aircraft is extremely strict on design and quality. Even a small loose screw can cause the aircraft to crash. People die. For example, a Qantas A380 aircraft carrying 459 people suffered an unexpected engine failure over Batam Island, Indonesia. Thanks to the pilot's skill, the plane finally landed safely, with little to no risk. We all know that the engine is the heart of the aircraft. If something goes wrong with it, the aircraft is basically finished.

Plane crashes are actually a small probability event, but judging from the weather and weather statistics, mechanical failure is indeed the main cause of plane crashes.
