Post Office Overseas Telegraphs or POOTS for short was the busiest and largest communications centre in the world.
Back in the 50’s, 60’s and early 70’s you couldn’t just pick up your phone and speak to a family member or work colleague on the other side of the world.
There were no satellites or mobile phones, so if you needed to communicate with someone urgently, you sent a telegram and if you were in India and wanted to send a telegram to someone in Australia, you probably sent it via Electra House in London. Because the whole world wide communciations network was centred on that one building on the banks of the Thames at Temple Bar. One terrorist bomb could have crippled the communications world but back then we lived in safer times and the idea never occurred to anyone, today such a centre would be unthinkable.
The staff employed at Electra house and later Cardinal House both operational and technical were some of the most competent in the world and as well as handling telegrams were also ‘Loaned’ out to other organisations such as NASA and the COI where their competence was highly appreciated.
