Has Air Canada responded and announced any disciplinary action toward the pilot. This is an unbelievable event ... the more I read the more convinced I am that the pilot/co-pilot were distracted and disconnected from their task.
Before being quick to crucify United keep in mind that they always call for airport security to do the actual removals. I'm sure they had good reason. Too many people are obnoxious and believe themselves immune from any discipline for failure to follow flight personnel's instructions. Little do they know.
