Tbh, most plane crashes happen in very abnormal conditions, as in it's rare for them to just drop out the sky. For example, the Indian crash today occurred on landing at a runway which was in a mountainous region surrounded by forest with a vertical drop off a cliff one side. There was no room for error, and even the most experienced pilots have experienced problems landing there from what the news seems to report.
It takes a culmination of lots of different circumstances that rarely occur to all happen at the same time for things like this to happen usually.
It's a conspiracy. Probably to do with LOST ending.
