Edward was not unique in his obsession with aeroplanes, but he was fortunate that his wife understood, or at least didn’t mind spending the summer touring round all the air shows in their camper van. The boys didn’t always go with them these days, but they had enjoyed a childhood of camping and exploring the British Isles.

A slight autumnal melancholy would descend on the couple as the air show season drew to a close, but the winter months were still busy for Edward, visiting air museums and doing research. Josie did not mind him spending long evenings on the computer, at least he wasn’t looking at pornography and she was free to watch her favourite television dramas.

Winter also gave Edward time to spend in his man den at weekends; this was no ordinary garden shed, but the sanctuary where he tinkered with his inventions. If his wife and sons had paid more attention to what he was creating they would have been very excited… or very worried.

Josie and the boys did not share Edward’s obsession with World War Two and the RAF. His special love, the other woman in his life, as Josie teased him, was the Spitfire, the most perfect aircraft ever built, a beautiful bird that pilots did not just fly, but became a part of. Or so Edward had read and heard from those who had flown them. His six foot four gangly frame, poor eyesight and asthma had precluded any hope of joining the RAF, let alone becoming one of the special few who flew with the Battle of Britain Memorial Flight. He was a frequent visitor to the BBMF visitor centre at RAF Coningsby and all the tour guides knew him well, too well; they didn’t always appreciate him volunteering extra information to their polished talks.

Edward had no idea where his Spitfire dreams came from, nobody else in his family had been interested in flying. Josie said he should consult a medium, perhaps he had been a pilot in a previous life, helping to win the Battle of Britain. In his dreams at night he was always soaring up into the blue sky, not diving down to a violent death. But as his wife pointed out, he could have survived the war and lived on for a good many years; Edward was born in 1970.

But Edward’s thoughts and day dreams went far deeper than his family could imagine, in his den were creations nobody knew about. Talk of time machines was outdated, Edward’s calculations and research pointed to folds in time and certain frequencies. His plan was to tune into the frequency of the iconic Merlin engines and his dream was to save lives; the Spitfire was built to fly not die, not kill. If he could bring the Spitfires forward to the present, before their pilots perished in the Battle of Britain, their young lives would not be wasted.

His theory became reality when he realised he could tune his adapted radio to hear the past, even if he could not see it. Edward had plotted meticulously the dates and air bases of that summer of 1940, but all the planes would converge to one date, the final day of the Sandy Cliffs Air Festival. The spitfires would fly in formation above the fields of Kent they knew so well.

There were only two drawbacks to Edward’s grand plan; the weather might be bad and he could change the course of history.

If it changed so he had never existed then he would never have been around to change it… On the other hand if he was alive and well to witness the proof of time travel, he would also be able to observe if history had been changed. If the pilots were taken away the Battle of Britain would be lost, but that didn’t mean WW2 would be lost. Edward had given this great thought; historic events weren’t a matter of one way or another, there were infinite possibilities at the start of every day. Whatever happened, it should be a jolly good show for the year of the RAF’s hundredth birthday.

The weather was beautiful, Edward could hardly contain his excitement. Josie had a headache and decided to stay in the shade of the camper van, the boys had come along reluctantly and were mooching around glued to their smart phones. They should all be snapped out of their languor at three pm.

The commentator also had a headache, the extra hot summer and too many air shows were taking their toll on his health. Wearily he turned on the microphone.

…and don’t forget the finale of the show at four pm with the Red Arrows and a few surprises, but now here come the Spitfire and Hurricane; on a sunny day like this in 1940 the sky would have been full of these beautiful planes… but

He took his glasses off and rubbed his eyes…

On the cliffs the crowd gasped in awe as tiny dots became little planes and more and more filled the skies above them…

Edward thought his heart would burst with pride, the formation grew in the orderly fashion he had planned. The commentator was silent, but suddenly crackled back into life.

Once again we celebrate the strange events of 1940 when German pilots reported the enemy planes disappearing into thin air in front of their eyes, day after day until they all refused to fly for fear they too would evaporate. And so began the slow process of conciliation and the creation of our great empire Gaul.

Edward looked around at the crowds waving strange purple and green flags and wearing clothes that looked unfamiliar. He rushed back to the camper van to tell Josie what he had done; he needed her to confirm what he was seeing.

A strange woman flung open the door, two little girls ran up to him.

‘Daddy, Daddy did you see all the planes?’

‘They certainly put on a good show this year Ed’ said the strange woman.

Edward realised a factor he hadn’t taken into account, he still existed, but the great mixing of the gene pool that occurred after the war and brought Josie’s grandparents to Britain had not occurred, or had occurred in a different variation…
