The wreckage of a World War II German fighter plane, with the remains of the pilot, has been found in Denmark by a schoolboy doing his history homework.
North Jutland teen Daniel Kristiansen had an assignment to study WWII. His father - farmer Klaus Kristiansen - jokingly told his son to "go out and find the plane that is supposed to have crashed in the field". Daniel took him seriously.
Mr Kristiansen told local radio station DR P4 his grandfather had spoken of a German plane crashing in the nearby swampy fields during WWII.
After a few days searching the area with a metal detector, Daniel found some plane debris.
Mr Kristiansen says they tried carefully digging with a borrowed digger.
"More and more parts came up and the further we went, the more we found."
They stopped when they found an entire engine block and bone fragments from a human.
Authorities were called, and an archaeological dig uncovered a Luftwaffe Messerschmidt Bf 109, with the remains of a crew member - presumably the pilot.
"And then we found some personal things - books, a wallet with money," Mr Kristiansen told the BBC.
"Either it was a little Bible or it was Mein Kampf - a book in his pocket. We didn't touch it, we just put it in some bags. A museum is now taking care of it. I think there's a lot of information in those papers."
The artefacts were smeared with kerosene when the plane crashed, North Jutland Museum archaeologist Torben Sarauw told DR.
In the wallet were three condoms, cigarette papers and a handful of coins, he said.
"My son now has something to write about for his assignment," Mr Kristiansen said.
