Back in the mid 70's I worked on the 10 series aircraft when SATA in Zurich had 3 of them for flying down to the Med and other places. Main memories were the indifferent Flight systems/ILS and having to sit on the wing and top up the fuel tanks for the longer range flights!!
SATA also had DC8-50's and 63's which more my cup of tea. In those days, 4 engines were good.
