NON-ENTRY INTO COCKPIT OF COMMERCIAL AIRLINERS FROM PASSENGER CABIN

My idea is simple.

Hijackers take control of airplanes by forcing their way into the cockpits by physical means or threatening to kill passengers or crew if the crew does not unlock the door between the passenger cabin and the cockpit.

Take away the door between the cabin and the cockpit and that takes away completely the threat of hijackers taking over control of the plane by force or coersion.

If they can't get into the cockpit...they cannot take over the control of the plane.

Yes, they can still blow up a plane if they can get bombs past security, but they cannot hijack the plane.

This idea was turned into the FAA and it's agencies before 911 and was rejected due to cost of refitting planes. But think about what it has cost the U.S. since 911 to prevent it from happening again.

If those terrorists had not been able to gain access to the three planes cockpits, 911 would have never happened.

If they do not want to retro-fit the planes, make the changes on new airplanes from this point forward.

Thank you for your consideration.
