I have been looking into the Avo Piht story to try to figure out where the various claims come from.
This article from Yle contains a lot of information. It has a photo of a list of survivors, which my machine translation suggests was posted in front of Tallinn's shipping terminal. (In Finnish: "Aamulla Tallinnan laivaterminaalin edessä liput ovat puolitangossa. Paikalle kokoontuu Estonian matkustajien ja henkilökunnan omaisia. Heitä yhdistää suunnaton suru ja epätietoisuus. Toimistovirkailija tulee kiinnittämään infopisteen ikkunaan ensimmäisten pelastuneiden listan. Terminaalissa syttyy hetkeksi toivonkipinä. Lista on valitettavan lyhyt, nopeasti ja harakanvarpain kirjoitettu. Pelastuneiden joukossa on kapteeni Avo Piht.") I have attached the photo to the post. You can see that it has Piht's name, though spelled wrong as 'Aavo Piht'. It does not have his date of birth.
In that article, the claim that all survivors had to give their date of birth comes from Captain Jüri Lember, who was in Rostock, Germany at the time of the sinking and thinks he saw Piht get out of an ambulance on TV. The machine translated sentence is: "In his opinion, only those who had personally given their name and year of birth were included in the list of names." (Finnish: "Lember sanoo, että tämä todistaa Pihtin pelastuneen. Hänen mielestään nimilistalle pääsivät vain ne, jotka olivat itse henkilökohtaisesti kertoneet nimensä ja syntymävuotensa.") So it looks like the source of the claim that all survivors had to give date of birth is just the opinion of someone who was not there and was not involved in the rescue in any way. (
Another article from a different website also attributes the idea of date of birth to Lember.)
As far as who saw Piht alive or listed him as a survivor, all we get is: "According to several unofficial sources, Captain Piht was first brought by helicopter to Utön island and then to Turku." (Finnish: "Useiden epävirallisten lähteiden mukaan kapteeni Piht tuotiin helikopterilla ensimmäisten pelastuneiden joukossa aluksi Utön saarelle ja sieltä Turkuun.") None of the unofficial sources are named or even described. This is it.
Oh, there is also this claim from Pirjo Peltoniemi, a retired journalist who used to work for Yle:
The closest thing to a witness in all of this is a guy who thought he saw him on TV.
There is
another article about whether Piht was rescued that focuses on Avo Piht's wife and her claim that she knows exactly how he was rescued. However, the article says, "'We cannot comment further on this letter,' says Sirje Piht, who does not explain where or how she received the data concerning Avo Piht." (Estonian: "«Rohkem seda kirja kommenteerida ei saa,» ütleb Sirje Piht, kes ei selgita, kust või kuidas sai ta Avo Pihti puudutavad andmed.")
It really looks like the initial sources are a list posted at an information desk in Tallinn and people who thought they saw him on TV. None of the articles I found have a better source.
Interestingly,
this article by Christopher Bollyn about Avo Piht contains all of the spin and misinformation that Vixen has been spouting, including the claim that Sweden "disappeared" two Egyptians in 2001. It is very light on sources, though, so isn't actually any help.
