The New York Times reviewed evidence that revealed strong parallels with recent 737 Max crashes.

In the 2009 crash and in more recent crashes that killed 346 people, an automated command was triggered by a single faulty sensor. The first crash should have dissuaded Boeing from using a similar design in the Max, one expert said. Instead, “the issue got buried.

In its final report, the Dutch Safety Board either excluded criticism of Boeing and instead primarily blamed the pilots, all 3 of whom were killed, for failing to react properly when an automated system malfunctioned.

They found that criticism against Boeing was absent, after the 2009 accident -which fits into a pattern of the company benefiting from a hands-off approach by safety officials.
