I agree.  As part of that, all pilot and co-pilot communications (personal and work) should be scrutinized by people who understand how coded messaging works.   Analyze the heck out of everything.

Air Canada seems to have a disproportionate number of "weird" events over the past few years.   Smoke in the cabin, cockpit, near misses, etc. etc.   There is something "funny" going on.   Would not touch their stock with a ten foot barge pole.
