See the toilet sign on the toilet door in photo 9? It is spring loaded and lifts to the top. Underneath is a latch that unlocks the door from the outside. Try it next time you are on a flight. It is FLCs´s dream come true, if he fits......

Standard on all commercial planes.

He usually travels "cargo class".

At a cruise of 35,000 feet we need to keep the cabin pressure below 75.8 KPA (11 PSI), the ambient pressure at 8000 feet. A main door slides on the horizontal plane and are locked & sealed on the vertical. At 35,000 feet, the ambient pressure is about 24.8 KPA (3.6 PSI) if the average door is 8 square feet, the pressure exerted on the door is about 4.25 tons.

The reason for the 8000 foot cap is to avoid nasties like altitude sickness, decompression sickness, hypoxia etc.

Newer commercial jets are somewhere in the range of 6-7000 feet equivalent cabin pressure & some executive jets are in the 4000 foot range.

I travelled on TigerAir in Australia and paid for the exit row in the middle of the plane. The cabin crew came past and asked if we could lift 15kgs, as that was what the door weighed. My first thought was, bloody hell, only 15kgs that is stopping the outside getting in?

It will weigh more than MF once it is airbound.

He usually travels "First class / Business Class", when performing the role of MF's "personal assistant".

HTH.

-

It's not so much the weight than the thickness of the skin that is interesting - on a A320 it is 1.1mm slightly more around windows and around doors, and their will be some additional structural integrity of a ´'torque box' in these areas.

Fun fact. The air in a 747 weighs over 1000KG and forms part of fuel loading calculations.

[WTFH]

Fun fact: There's a difference between 22,300kg of fuel and 22,300lb of fuel.
If you're ever on flight AC143 (Montreal to Edmonton), make sure the pilot knows that as well.
