Secrets Your Pilots Know -- But You Don't

Pilots communicate with flight attendants via a bulletproof door.

It’s true that pilots have a bulletproof door with a special security code on it. The code will work if a pilot doesn’t take any action within 120 seconds after the code had been entered. It is done in case all the people in the cabin pass out due to depressurization, for example. In regular situations, stewardesses cross-check pilots over the phone. They must do it every 40 minutes during the day and every 20 minutes at night to make sure of their working capacity.
