The "Sud-Aviation" Caravelle had 5 seats (3 + 2 ) facing rear on the first row.
This type of plane flew from 1955 until 1992 (for the lasts variants ) with many Airlines around the world, including the U.S with United. It was the first medium range jetliner ever built and can be considered as the ancester of the DC9, as it was also the very first rear-mounted engines aircraft.
Air Inter, the French domestic Airline (now merged in AF
) was the last big European Airline to operate the last 12 "Caravelle Super XII" until 1992.
People used to love these facing back seats ( on the right side of the plane, you were 3 facing 3, like in a train...very friendly ), some others HATED them and made big drama to seat there, when the plane was full...
The three rear facing seats were on the left of the picture, the two others were on the right of the picture, and were separated from the two facing seats by the main entrance door.
