I watched the unexplained deaths of drummers in Spinal Tap, which does help explain Boeing's obfuscations.

In related news, it seems the authorities have been reading your list of mishaps.

9 News: The US National Transportation Safety Board (NTSB) is issuing "urgent safety recommendations" for some Boeing 737s, including the embattled 737 Max line, warning that critical flight controls could jam.

"Boeing's 737 flight manual instructs pilots confronted with a jammed or restricted rudder to 'overpower the jammed or restricted system (using) maximum force, including a combined effort of both pilots,'" the NTSB said.

That doesn't sound very safe. What if one of the pilots is a weakling?
