Liverpool tribute appears in English countryside

That's probably not the work of a UFO.

In the lush greenery of the Shropshire countryside - a 15-minute drive from the culinary hub of Ludlow - Ordnance Survey employee Andrew Tyrrell, a remote-sensing surveyor and air-camera operator, spotted the letters "LFC" carved into Titterstone Clee Hill earlier this week.

"I think we can safely rule out aliens on this occasion," Danny Hyam, a member of the consultancy and technical services team, told the Ordnance Survey's Keegan Wilson. "Perhaps there is someone living in this area who supports Everton and has a back garden or bedroom window with a view of the hill and has a Liverpool supporting friend with an extreme sense of humour? It is one of the most unusual ways of showing support for a team I've ever seen."

The letters appear to be around 85-95 metres in length from the air, but could actually be 100 metres - the length of a football pitch - when the slope is taken into account.

The tribute was spotted a two-and-a-half-hour drive from Liverpool's Anfield home.
