Delta Air Lines 19 1 Flight Accident Investigation

After a long investigation, the national transportation safety board (USA) thought that the accident could be attributed to the pilot's mistake, because they didn't give up landing in bad weather until it was too late to find that the situation was worse than expected. However, the investigators found that the storm near the airport formed quite quickly that day. After a business jet that landed one minute earlier than 19 1 arrived at the airport, the crew of 19 1 flight thought that the small business jet could land and their Samsung passenger plane could land safely. But in fact, the storm formed quickly after the small commercial plane landed, and even the ground radar failed to detect it. Until the airport tower found that it was too late to inform the crew of flight 19 1 to fly again.

Combined with weather factors, microburst is the main cause of air crash.
