Nope - it actually happened ! Jack and Jill windmills are very real and present and one of them did catch fire during the storm.....
".....At least, that’s what Simon Potter of the Jack and Jill Windmills Society did on October 16 1987 when smoke and sparks “like comets” were seeing pouring out of Jill.
Simon told the Mid Sussex Times that he was called at 5am by Vera and Robert Deering, owners of the Jack windmill, who gave him one terrifying message – Jill windmill is on fire.
With all roads to the mill blocked, Simon and a neighbour scrambled up the side of the Downs, crawling on their hands and knees to prevent being blown over in the howling wind.
When they reached the top, the mill was full of smoke."

"...... Inside, we tried again to stop the sweeps, then we noticed that there was a glow from the front corner of the mill, and that the body of Jill was on fire. I rushed to a fire extinguisher and pushed the plunger - only a trickle came out!
Water became the next priority, while I continued to try to stop the sweeps Robert and Peter ran back to the house and started to ferry buckets of water up to the mill."
