A helicopter crashed into a tanker full of diesel fuel on Monday, but all three members of the crew survived.
The small helicopter slammed upside down into the cab of the truck and just missed its tank, which was carrying 7,000 liters (1,850 gallons) of flammable diesel fuel, said the district police's operations leader, Rune Arneberg.
There was no one inside the truck, which was parked at a construction site.
"It's pretty incredible," Arneberg said by telephone from the southeastern Norwegian town of Sarpsborg. He said there had been no fire and no leak from the fuel tank.
Arneberg said all three men aboard climbed out of the wreckage on their own. One of them then lost consciousness and was flown to Ullevaal Hospital in Oslo for examination, although his condition was not immediately known, Arneberg said.
He said the pilot suffered minor injuries and that the third person aboard was unhurt.
