In 1989, an Air Ontario aircraft crashed shortly after take-off from Dryden (Ontario, Canada) Municipal Airport during heavy snow.

In this case, the airline's cabin crew essentially had been trained to trust flight crews' judgement and not to question it. Certain captains tended not to treat seriously operational concerns expressed by flight attendants. Moreover, company flight attendant training had no technical content about the effects of snow and ice on lift. Studies concerning this specific accident revealed that the pilots and the flight attendants had respect among one another as friends but when it comes to working as a crew, they don't work as a crew. They work as two crews. You'd have a front-end crew and a back-end crew, and cabin crew are looked upon as serving coffee and lunch and things like that
