A helicopter apparently being used to photograph a construction site in Rudskogen went out of control before crashing upside down into the cab of a tank truck.
There were several eyewitnesses at the site who watched the accident in disbelief.
"They opened one door to take pictures. We stood and watched the helicopter when it tipped over on one side. In a flash it crashed into a tank truck that was sitting on the plain," said Bjørn Gunnar Torp and Geir Knudsen.
Witnesses said that the helicopter circled over the area for about 15 minutes before the crash.
"It was a very unusual thing to watch. We didn't understand a thing until it was all over," Knudsen said.
The two men said that they regularly see the helicopter over the area, the developer uses it to photograph progress on the site.
Ole Johan Sparby, another worker at the site, saw the helicopter hovering low just before the accident.
"A person was filming or photographing from the door opening. The helicopter suddenly started to rotate, then it flew sideways into the tank truck. Then it smashed into the cabin and lay there upside down," Sparby told Aftenposten.no.
"The person filming managed to get out on their own. The other two hung there in their safety belts and had to be cut loose. The whole thing was quite scary," Sparby said.
The truck was empty at the time. The three people in the helicopter were taken to hospital but police said that none of them had suffered serious injury.
