NTSB chief rips Boeing over lack of 737 Max answers

The head of the National Transportation Safety Board (NTSB) took aim at Boeing for a lack of answers connected to a midair blowout involving a Boeing 737 Max earlier this year.

A door plug on an Alaska Airlines flight earlier this year blew off while in flight, prompting investigations into how the plug was able to tear off the Boeing 737 Max. In a preliminary report released earlier this year, the NTSB said four bolts meant to help secure the door plug were missing after it was opened for rivet repair work in September.
