It was a plane from the flight school Pilot Flight Academy in Sandefjord that crashed in Larvik on Tuesday last week.
On board the plane were instructor Goran Neskovic (30) from Oslo and students Filip August Müller Frich (21) from Dombås and Eirik Paulsen (22) from Bodø. The names will be released in consultation with relatives in a press release from the police on Tuesday.
The plane was completely wrecked and it quickly became clear that there was no hope of finding survivors.
The police have been in contact with the next of kin, who are followed up by crisis teams in the respective home municipalities.
