Dr. Edwards, who speaks and reads German, did not issue a formal report but commented verbally and by letter to Brian Braidwood. Dr. Edwards’ comment was:
»"I looked over the film and the hole in the starboard side is clearly a petalled hole. This is typical of what happens when a thin plate is subjected to an explosive charge. The charge has not been in direct contact with the ship plate (if this had happened the hole would not have been surrounded by the relatively large petals seen in the film).«
Brian Braidwood asked Dr. Edwards whether he would be prepared to endorse the following extract from his report, to which he agreed:
»From the Brandenburg reports, I can now conclude beyond reasonable doubt that:-
1. The structural deformation of Sample 1 was caused by an explosion.
2. The increase in hardness measured in Sample 1 was caused by an explosion.
3. Overall, the findings of these technical reports are further evidence that there was an explosion in the ESTONIA, in the vicinity of the starboard forward bulkhead from which Sample 1 was taken. «
For further details reference is made to the report of Brian Braidwood attached as Enclosure No. 5.
