HAS a UFO been spreading a message of love over North East Lincolnshire?
Or is there a more down-to-earth explanation for the strange heart-shaped contrails spotted by our eagle-eyed photographers this morning?
Among the readers to have called in already with their theories is Philip Greenfield, who said it had been a pleasant surprise to see the shapes appearing over Waltham Windmill.
Speaking as he watched the trails being formed, he said: "I think they must be jet fighters, as they are so high up.
"One has just come down a bit lower and I think it's probably a Eurofighter from RAF Coningsby."
If you have your own theory – or videos and pictures of the contrails – please call the newsroom on 01472 372236 or email pictures@grimsbytelegraph.co.uk
