With last year's attacks on the people of freedom and common sense, hopefully security will be more closely watched, but if dan or mary decide to have a bad day at work, we don't have to worry about a simple slip up because everybody that gets on the plane has no access to the cockpit during take-off and landing and if someone decided to cause a problem then the entire passenger section will be put to sleep. - End of problem!!! I think it's a safe way.
