A mystical ring which appeared in the Norfolk sky
on Monday 1 March has been explained by air traffic control at Norwich
Airport.
A US military pilot carrying out an air test at
35,000 feet - about six and a half miles high - flew a perfect circle
above Dereham.
The weather conditions meant he left a vapour trail
which could be seen from as far away as Norwich.
People from across the county have sent in their
photos of loop in one of our most popular photo galleries ever.
Thanks to everyone who sent in their snaps.
Young photographer
Benjo moved away from the trees to get this second photo.
Brian
took this snap of the ring over Daffy Green, Scarning.
David
Adams captured the circle on his camera as he was leaving
work at Wymondham.
You
can see just how bright the circle looked with David Adams'
second image.
