Exactly. And the Germanwings catastrophe is an excellent example how locks can be misused. And please, just because of one single event in 115 years of powered aviation, do not make life more complicated and annoying for all of us. We have enough locks and security checks and protocols and procedures and IDs and keycards in place to take most of the enjoyment out of our profession.
