A farmer’s apology to his wife for being grumpy has gone viral after the giant message was spotted by a police pilot.
A frenzy was sparked on social media, spawning the hashtag #WhoIsSue, after the letters "SUE x" were spotted by a police pilot flying over Oxfordshire.
Mystery Sue has been revealed as the wife of farmer Murray Graham who created the message as an apology for being ’grumpy’.
His son George said: "I suppose Dad wanted to express his love in the most creative way he could."
George is a pilot and the farmer wanted him to take a photo but the National Police Air Service beat him to it by tweeting ‘does anyone know Sue?’.
Twitter and Facebook users quickly got to work and began tagging Murray and his wife into social media posts about the mystery.
The Twitterati explored various theories, ranging from aliens accused of making crop circles wanting to "sue" for defamation to a PR stunt by the Field Museum, which houses a T-Rex skeleton called SUE.
Andy Ford, a geography lecturer at Bournemouth University, revealed that the message on the 15 acre field was even visible from space and could be seen on on a satellite image.
Mr Graham told The Telegraph: "I’m not as bad as I make out and I do love her really".
He added: "I sprayed it the best part of two weeks ago - it takes a while for it to become apparent. I said to George ’when you’re down there see what you can see’, and I didn’t tell him what it was.
"My other son was working down there the other day and said the police helicopter was going around and around, and we didn’t put two and two together."
"I had some leftover chemical and I thought I’d give it a go and see if I could put a smile on her face," he said.
"I’m quite surprised. I didn’t expect it to go national or international or even intergalactic."
