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.
George Bencze
sent in this photo of the ring in the late afternoon sky over
Norwich.
Here's
another one from George Bencze.
George
Joy captured the ring in perfect form over Attleborough.
The
loop looks like it's almost turning around in this second
shot by George Joy.
