RAF Marham today ruled out any possibility its aircraft had sparked a flood of UFO sightings.

Witnesses have reported seeing bright orange lights in the sky at locations including Dereham, Downham Market, Holkham, Caister and Norwich in recent days.

News of the sightings comes a week after a helicopter pilot had reported seeing a strange orange light over in the sky over Norwich.

Dennis Sayer, from Dereham, said: 'Me and the wife spotted an orange light passing our house here in Dereham from the Windsor Park area about 11.15 Monday night looking out from a bedroom window and it was coming from the Norwich area heading toward Fakenham/Wells way.

'It did not appear to be going that fast about the speed of a helicopter or less .I tried taking a picture of it with my mobile but the light was not bright enough it was orange and pulsing and what looked like other coloured lights within it, but the main colour was orange.

'It did not seem that far out in the sky maybe a couple of miles out and like I say it was not travelling that fast because when my vision was blocked by trees I had time to run down stairs unlock my front door and go outside and continue watching it go past.'

Helen Liddell, from Denver, near Downham, told a UFO-watcher's message board: 'My husband and I were standing outside our back door when we saw a large orange light in the sky seemingly coming towards us.

'Initially, we thought it must be some kind of plane, however, there was no noise at all. The light then changed course and moved horizontally, flickering at times, it remained visible for 51 seconds and then disappeared.'

One poster from Norwich said: 'Strange bright orange light moving through the thought it was a plane but it moved very fast came from over Norwich then stopped and seemed to go upward into the sky and disappeared. Nine more followed.'

Another, from the city's Stirling Road, added: 'Bright light shooting across the garden at around 40ft from the ground. It was more in keeping with a firework than anything else. Saw something very similar a couple of months ago in the same location.'

A spokesman at Marham said none of its aircraft were in the air at the time of the sightings, which have occurred over the last 10 days. Norfolk police said they had not received any calls about the lights in the sky.
