The passenger cabin
That's the interior of the Super Connie.

There are a couple of strange things to see. First of all the rings and hooks on the sidewalls... it doesn't look like a luxury airliner.

The reason is simple. The Breitling Connie used to be a military transport airplane. It was built to transport troups, cargo and also wounded soldiers. The seats are easy to remove and through the big freight doors it was possible to load bigger items. The ring were used to secure the cargo.

There was no carpet in those days...

This is an example of a cabin interior from KLM. It's the VIP lounge at the rear of the cabin. In the Breitling Connie it's the place where the toilets are.

The interior was very different from airline to airline. A maximum of 100 passenger seats was possible.

There have also been airlines who equipped some of their airplanes with beds, for example Air France with it's President Class. Some configurations had place for only 20 to 30 passengers.... flying was a luxury in those days.
View in direction to the cockpit.

On the left side is the radio rack where all the electronics for navigation and communication is installed. Most of the devices are not connected anymore. They have been replaced by modern equpiment like the Garmin 530 GPS.

On the right side are the bunks for the crew on long distance flights. The three seats in front of the bunks are reserved for the flight attendants.

The long red rod behind the seats is a crank to manually move the landing flaps in case the electric actuator fails.

The rear passenger door.

The dark grey cylinder with the yellow handle serves to open the big cargo door. It swings out together with the passenger door.

The yellow line in the upper left corner of the picture is the upper edge of the cargo door.
