No, I am not saying that at all, although where the captain, Avo Piht was and is, is quite mysterious. There is actually an Interpol warrant out for his arrest, even though he is supposed to have sunk with his ship.
Have a look at this youtube video:
estonia the find that change everything- episode 5
(Although it has an age warning, I couldn't see anything that would be disturbing to people not already aware of the topic.)
It explains how the case came to be reopened. The journalist,
Henrik Evertsson, who led the German/US/Swedish film crew to the site to film the hull - who should receive a prize for investigative journalism - was recently cleared of disturbing the grave. He was shocked to discover the hole in the side 'where the passengers' cabins would have been located'.
He took his findings to various experts - as portrayed inthe video, above - including an army explosives expert in marine bomb/torpedo damage (he referenced
USS Cole). He said looking at the detail of the hole, he didn't think it had much similarity to explosive damage he had seen, as the metal should have curled over inwards more (it was indeed folded over flat at one spot). Evertsson, then took it to a mathematician who modelled a near life-sized three-D version of the damage Evertsson had filmed. It spanned from floor to ceiling and was as wide as a window frame. Next, he took the modelling to
Professor Jørgen Amdahl, some kind of physicist, who offered to calculate the force needed to cause such a dent and rupture. He had originally said the damage could have been caused by some solid structure floating in the sea...such as the bow visor. After he had done some intricate calculations involving velocity and force, he concluded that the damage could only have been caused by an object weighing 1,000 tonnes, travelling at about 4 knots (
Estonia was travelling at about 14 knots), such as a small fishing boat...or an object weighing 5,000 tonnes travelling at 1.9 knots...such as a submarine. He explained that submarines come in all sizes from 1,000 tonnes to tens of thousands of tonnes. He was pretty shaken by his findings, as he discovered the bow visor weighed just 55 tonnes. The professor opined it would need something like twenty times the weight of the bow visor to have caused that type of damage.
Do watch it for yourself as it will answer a lot of your questions.
