Plenty compared to the set of airliner crashes, which is very small. There are also a lot of near misses that don’t turn into crashes precisely because of pilots being good at their jobs.
For AI to replace pilots, you don’t need to prove that sometimes humans fuck up. You need to demonstrate that AI would fuck up less often and in a more acceptable way. This requires looking at the big picture, not only bad cases.
Maybe for cargo. But there's zero chance that single pilot operation will be allowed for airliners. The workload for managing emergencies is too high for a single pilot, even with extensive automation.
