Alf Ingesson Thoor has worked in the air force for 50 years and has also worked in accident investigations, including as a witness psychologist.
Together with the aviation historians Göran Jacobsson, he has written a book about Swedish accidents with a fatal outcome during the Cold War and is now working on sequels about the period between 1926-1945 and after 1990.
They have studied the case of the wrecked Swedish bomber that crashed on the ice on Lake Poustijärvi outside Övertorneå on February 3, 1943.
Misjudged the height
According to them, the crash was an accident and that there is no support for the theory of a shoot-down launched by author Lars Gyllenhaal and Kiruna divers Roine Norström and Simon Kenttä.
They believe that the sequence of events is well mapped and documented in the accident report.
It must have been that the pilot, when following the terrain, must have misjudged the height and collided with the snow-covered ice at a relatively steep angle.
- For the sake of the relatives, it is a sensitive matter that one does not speculate too much, says Alf Ingesson Thoor.
Many question marks
Lars Gyllenhaal has heard the arguments from Alf Ingesson Thoor and Göran Jacobsson.
He maintains that there are many question marks surrounding the incident and that there is reason to continue to try to bring greater clarity, not least with regard to the relatives.
- The relatives we have been in contact with have been grateful for our research, he says.
