People living in the village of Gillingham have been speaking about the moment a helicopter crashed, killing four men onboard, including millionaire peer Lord Ballyedmond.
Today air accident investigators are examining the wreckage and crash site.
The helicopter in question was often used to ferry workers over to the hall, they were staying here as residents as well. They were doing all kinds of work up there, carpet fitting, decorating, general stuff.
It made us open the back door because the sound was so loud and slow, but it was gone 8 o'clock. Really loud, not like the usual helicopters you hear and you couldn't really see because it was so foggy.
41-year-old James Tuttle who lives in nearby Geldeston saw the helicopter come down.
We used to see him coming and going in his helicopter from our back garden all the time. At about 7pm we noticed the helicopter coming in very low and at an unusual 45-degree angle. We didn't hear any bang or explosion, it just seemed to be flying in a strange way. The fog wasn't bad at the time, just patchy, it only got worse about an hour after the crash happened.
As the fog lifts around Gillingham near Beccles, the crash site can be seen from the Norwich to Lowestoft Road, the A146.
Air accident investigators are at the scene of the crash, examining the area.
The helicopter came down in the field close to the well known McDonalds roundabout.
