The English language news release was published several hours later than the original Finnish language breaking news, so I knew the reg (HN-468) and the details before posting. The pilots were on a test flight like I said, the broadcasting company have it wrong (it figures)... anyway, here are some pics of the crash site, published by the Air Force, also confirming the aircraft in question:
Puolustusvoimat - Frsvarsmakten - The Finnish Defence Forces
The pilots have been operated due to fractures recieved, and are recovering OK. Nothing left of the aircraft except for a hole in the ground....
