Oh loooky, you get it from a heavily CT website. Surprise.
Subsequently they went out with a PAN PAN message which means 'Man Over Board' and only later with 'Mayday' after they had sent out the PAN PAN. This was Helsinki Radio.
T: PAN PAN. It is not as heavy as a 'Mayday' call. This is used when somebody has fallen overboard, for example, when there is no danger for the vessel itself.
A "man overboard" is NOT a valid reason to use a PAN PAN call, and the "no danger to the vessel itself" part is flat out wrong. Which leads me to question to reliability of the rest of it. The whole "the statement from memory of one person outweighs four others, and the comm logs, and the recordings" thing (in that case I would assume it was said person who got it wrong), and spending paragraphs widely speculating and details and assuming them accurate in the complete absence of evidence they occurred at all does not strike me as solid reasoning. That the whole thing is based off of a "Mayday received 30 minutes earlier" based on an
anonymous phone caller to an unsolved mysteries TV show, with no verification it's not a prankster or hoaxer, things which are rather known to exist in these types of things, assuming the TV show didn't just make it up themselves, which also happens. (About that "believing your TV thing...").
Also, a Swedish operations log would be in Swedish time as a matter of course, so I suspect a time zone differences not accounted for are a source of much confusion. For example, a helicopter flight from Sweden that would take 40 minutes to arrive with the takeoff time recorded in Swedish time (as it would be as a matter of course at the base) with the arrival in Estonia local time would then appear to be be an 1:40 long flight. And an ETA of 3:03 or so in a Swedish operations log would be equivalent to an ETA of 4:03 at the site of the wreck.
Also, I don't know how Q 64 could be on an early secret run, since there apparently isn't a Q 64. There's a
Y 64, which kind of matters since "Q" designated Swedish search and rescue helicopters that naturally would be the first called up and were properly trained and equipped, and "Y" designated military anti-submarine warfare helicopter that happened to have (largely defective as it turned out) winches for search and rescue as well, and
did not even have rescue men as regular members of the crew. Naturally the "Y" helicopters would only be called up in an extreme emergency, and the need for them didn't seem to be realized until the first helicopters were already on the scene, so a delay is natural.
And you still can't get the difference between helicopter, pilot and rescue man. Sigh.
