I’ve held off writing about the Air China flight which lost cabin pressure and quickly descended 21,000 feet because there were missing pieces to the story that just didn’t make sense. The incident was being blamed on a pilot smoking in the cockpit.
While it’s understandable that a pilot doing so wouldn’t want to be outed out of fear for their job, it was not clear how the smoking was in any way related to the incident. Until now, that is.
