With flight attendants, opening the aircraft door is an error waiting to happen. The captain listened to the problem and asked the flight attendant to make sure the door was disarmed. He then instructed the flight attendant to open the door, remove the strap, close the door and try arming it again. Although the flight attendant was cleared of any wrongdoing (officially, the door experienced a mechanical failure), he felt tremendous remorse. I know this to be true because the flight attendant in this particular ISD incident … well, he happens to be me.
