Grandad Dunham’s Flight Simulator

SGI Dogfight for the IRIS workstation

Like something from the future, it was the most amazing colour graphics workstation I had ever seen. I had got a job in a university where it was used to understand complex proteins by constructing and manipulating computer-generated images of the kind of ball and stick molecular models photographed with Watson and Crick in the nineteen-fifties. These models give insights into life at the sub-microscopic level, such as how molecules of oxygen displace molecules of carbon dioxide in haemoglobin. The details are so magically implausible you could come to believe in creationism. One researcher was moved to tears on seeing for the first time an image of part of the antibody she had been working on for three years.

It was the nineteen-eighties. The workstation came with a set of demonstration programs, among them a flight simulator. It was well in advance of anything any of us had seen before. The best you could have at home at that time, which replicated the dynamics of flight and motion with any reasonable accuracy, were black-and-white wire-frame simulations such as ‘Aviator’ and ‘Elite’ for the BBC Computer. The workstation simulator had coloured graphics and a choice of aircraft. You may now pause for a moment to speculate about the relative amounts of time we spent flying aeroplanes and modelling proteins.

At first, I was the only one who could land the Jumbo Jet without crashing. I had not wasted hundreds of hours flying under the ‘Aviator’ suspension bridge for nothing. I was one of the glorious few to have fought my way through to the secret code for my ‘Elite’ badge. What the others did not seem able to grasp – and some of them are now eminent professors – is that the pilot of a Jumbo-Jet sits the equivalent of three storeys high. You are still thirty feet up in the air as you touch down. If you try to land with your seat at ground level you will be too low, and smash into the runway with terrific force and die.

It all seemed terrifically futuristic. Yet my brother had a flight simulator twenty years earlier in the early nineteen-sixties. You might call it Grandad Dunham’s flight simulator. How could that be? Grandad Dunham was our great-grandfather who died in 1941. He spent the last two years of his life living with his daughter’s family. When he moved in, his son-in-law carried his chair through the streets of the town on his back.

I now have that very same chair, twice refurbished, and very comfortable it is too. On its back and covered with an eiderdown it makes a wonderful aeroplane cockpit. My brother played in it happily for hours. Sometimes he would let me be his co-pilot. He chalked some controls and instruments underneath the seat. They are still there after sixty years.

What makes it particularly poignant is that my brother died at thirty-six. The grandchildren he never saw are now about the same age he was when he drew those simple chalk marks. They can have all the latest tablets and smartphones, and simulators so realistic you forget they are only software. But one thing I do know. No matter how advanced the technology, it will never be one-half as much fun as Grandad Dunham’s eiderdown-covered chair with the chalk marks on its upturned seat.
