A Norfolk resident has tweeted about hearing a helicopter flying over his house in thick fog tonight, while taxi driver Mark Murray, 22, from Beccles, added: "There is a large stately home nearby and you often see helicopters coming and going from there.
"When they have a game shoot the guests often all arrive in separate helicopters. We don't know if that is linked, but that's the only helicopter activity we see in this area."
Helicopter crashed very close to my house in Gillingham tonight. I heard it flying over the house
In Gillingham now. Can't see my hand infront of my face. No sign of scene of crash. Wouldn't see it anyway, too foggy
