A Finnish company examined the bow visor for traces of explosives but found none. However, the same thing happened with the TWA 800 bomb on an airplane that crashed into the Atlantic. As the wreck had been in the water for seven days, it was no longer possible. The
Estonia had been underwater for seven weeks so it should have realised tests won't be able to identify the chemicals.

This is why the German Group arranged for metallurgical examination instead.
Three independent laboratories confirmed that the twinning deformation found in the
Estonia bow bulkhead port side panel showed the force of an explosion in its structure. The BAM sponsored by the German government didn't even test the panel from the
Estonia. It used an ordinary panel and tried to recreate the twinning by other means (shot peening) which the
Estonia had never had done, according to records, and was of a superficial nature.
