Margus Kurm, former public prosecutor and former chairman of the Estonian government's investigation into the Estonian disaster, told Estonian media that M / S Estonia probably collided with a Swedish submarine, something that Sweden's former defense minister Anders Björck (M) doubts.
Björck is supported by Commander Nils Bruzelius with long experience of the submarine weapon.
He has been a submarine captain, defense attaché and also worked in the operations management at the Armed Forces' headquarters.
He is very determined in his opinion and goes even further.
He excludes that Estonia was damaged by a foreign ship at all.
- It seems to me to be completely out of the question that she was sailed on by either a submarine or a surface water vessel that has not been noticed.
On a scale of 1 to 10. How confident can you say you are?
- I'm completely sure.
If 10 is the highest, then it's 10.
He also rules out the possibility that other nations' submarines in the Baltic Sea may have damaged Estonia.
Russia, Poland, Germany and other nations operated in the Baltic Sea at that time.
- I'm completely sure.
We can exclude boarding.

"Damaged by the bottom"
Nils Bruzelius has researched at the Royal Institute of Technology (KTH) and has been employed at the Swedish National Defense College where he has taught future officers in marine technology.
Bruzelius is convinced that the big hole that documentary filmmakers discovered in the hull of Estonia arose when the ferry dropped the bow visor and sank.
- There is probably a reason that the damage occurred when the ship hit the bottom after she has sunk from the water surface.
It is thus a several thousand ton body that comes down to the bottom.
It is very likely that damage will occur in such a collision.
But if it is the bottom that consists of dy?
- It is clear that there is sediment at the bottom.
But the bottom condition at the site is the same as in the Stockholm archipelago and the Åland archipelago.
It is the rock bottom abraded by the ice sheet.
On it is a thinner or thicker layer of sediment.
When this several thousand ton heavy hull comes down, it hits the sediment and also the underlying rock.
Bruzelius also contradicts some descriptions that Estonia sank very quickly.
- I'm surprised it did not go faster than it did.
