Wait for what it, wait for it, wait for it, wait for it, ok here comes the obvious... I imagine we'll learn that the Air Canada pilot is from Quebec with a limited understanding of English. Of course if this is the case, AC and its pilots union will do what they can to HUSH the issue.

Most thankfully a traffic controller at the airport noticed what was happening and averted what could have been the largest passenger aircraft crash in history - 5 plane loads of passengers.
