And in at least one canadian one, who if anyone appears to be the party with the true “flaw” in their security (but it’s really just a systemic weakness, and sadly one I expect will be ended because of this dickhead’s meddling). It’s actually a fascinating story - he was given the ability to set up credentials as part of his job (or was able to re-submit himself for a second set somehow, I’m reading conflicting accounts of exactly how it was done), then just set up an alternative identity for himself that persisted after he left. As far as I understand it the identity was legitimate, it was just never removed from the system so he simply continued to use it. Probably the most interesting thing is that it’s so common for pilots and flight attendants to fly inter-carrier, I would not have expected it to be as abusable as it turns out to be.
