The world's oldest pen pals have both become 100 years old after many years of transatlantic letters and have now switched to Zoom. Centenarians (百岁老人) Geoff Banks from Honiton, Devon, and Celesta Byrne from the US, started writing to each other aged just 16 in 1938. They met as part of an educational project to put British and American students in contact — and decades later they are still corresponding. 

Former engineer Geoff even kept in touch with Celesta during WWII when he served as a mechanic on British aircraft carrier HMS Illustrious in the Pacific. It has been so long that Geoff, a retired engineer, barely remembers how they started talking. Geoff said, "I honestly struggle to remember how we got in touch, and I think it was something to do with an American school's scheme. It matched us up with Americans for a pen pal relationship, and somehow I ended up with a letter from an American girl, and we have just kept corresponding ever since. There were a couple of years when we struggled to keep in touch because of the war. Now I correspond mainly by email. Email is much easier for me these days because I can't write very well anymore. We just talk about daily lives and our families really, but we don't discuss the football. "

They now touch base via video app Zoom. Geoff said, "I have this new thing called Zoom to chat with her, but I leave all the technology to younger people. They're much better at pressing all the buttons. "

Despite having chatted for decades, the pair only met twice — first in 2002 while Geoff visited New York aged 80, and then again two years later. Having such a unique relationship, the pair deny there is any romance there. Celesta said, "We're just friends, like people who live next door. It's nice to hear his voice. "
