A microlight pilot flying over Buckinghamshire spotted huge letters in a farmer's field that spelt - 'F*** BORIS'. Pilot Ben Davis , 42, captured the expletive message from the side window of his microlight aircraft as he flew between Buckingham and Gawcott. Aircraft technician Ben believes the message was mowed into the field ahead of the British Grand Prix to be seen by helicopter traffic going to the nearby Silverstone race track. He posted the video on TikTok under the online moniker @bendavis79, as Prime Minister Boris Johnson faced a multitude of resignations from ministers. Ben, from Buckingham, said: "Something caught my eye as I was lining up with the runway to land back at base after a day out to France. Someone has been creative with their mower in a field. "I didn’t know it was there beforehand. A friend, who I was flying back with, had just landed ahead of me. I was lining up with the runway and it just caught my eye. "So I cancelled my approach and circled around the field. "One theory was it was put there for the helicopter traffic, coming up from London for the British F1 at Silverstone. They would see it as we are very close to the circuit here. "You hear of these things happening of late. My flying pals have been spotting fancy crop circles, but I don’t think this one was to do with aliens!" The video was filmed on June 29th.
