Evidently it started way prior to Internet or any other networks. It started with published paper version of flight schedules and people could then pick up phone and call the ariline. Same way it worked for travel agencies. The fact it was published on paper wasn’t as bad per se. The real bottleneck as it became aparent later on – the reservations were simply written on paper cards by ariline staff and placed in the pile with other ones till its time.
Absolutelly the pace civil aviation was evolving could not let this method survive. There were more and more flihgts and scheduling became more complex and it was just impossible to do things that way. The pioneer in computerizing reservations was
They built Reservisor, a system that let airlines store and then access seat reservations on magnetic drum.
It actually worked fine and the improvement itself was apparent – airline staff could manage reservations way easier, but there was still one problem, it was not connected to any network. Acrtually there was no networks in 1946 when the system was implemented. So the typical usage scenario would be: travel agent or airline user calls airline on phone and then they look it up in Reservisor.
This innovation was followed by another. This time by
It was in 1953 when AIR Canada started working on remote terminals. First they used Mark 1. This computer itself was pretty revolutionary ‘coz it was first time wh ere index registers were used, so it was way easier for software programmers to refer to memory elements (words).
It was a good step forward, but not very good. It became apparent that input and output are not working reliably, the main reason why Mark 1 was used by Air Canada.
