Ok, read the articles and some more for background knowledge.
So here are my 2cents.
[...]
Now the propaganda shifts to the grounding/collision story... still clutching straws. Ever seen a ship break amidship due to grounding without any damage in the front? lol. That means the ship must move sideways! It must take a very good North Korean civil engineer to achieve that.
[...]
Moving sideways is actually very simple for a ship. It happens when changing course or turning is conducted. Just inertia.
And thats also the reason why "no damage to sonar dome" is no conclusive indicator of the absence of grounding. On the other hand the scratches on the side of Cheonan are no conclusive indicator of grounding, since they may as well be obtained when the 2 parts scratched the ground after sinking, due to inertia or currents or a combination.
Only too happy to be of help
Probe concludes torpedo sank South Korea ship: report | Reuters
This was a press release during the investigation on May 6th which talks about German made metal and chemical residues.
The following are links relate to the Minority report.
Link 1 just gives proof that he was a part of the investigation team and that the Govt wanted him out due to his "uncooperative attitude".and also gives a bit of bio.

[¼*ÇÁ¶óÀÌÁî] Letter to Hillary Clinton, U.S. Secretary of state (µ¶°íŹ)
Make what you like of his allegations, but what nobody can deny is the wealth of detail, especially Oceanographic, which he provides. This is the kind of level of detail you would expect as a minimum for a report which has such serious potential consequences.
Imagine therefore my surprise; to put it mildly, when I read the official International report.
http://news.bbc.co.uk/nol/shared/bsp/hi/pdfs/20_05_10jigreport.pdf
All I can say is read for yourself and judge.
Ask yourself seriously, which document you you want to take with you if you had to argue your case in court?
Bur where is the Provenance? The photographic evidence does not even make it into the Final report. We are asked to the take its provenance on trust, but given the woeful state of the chain of evidence, that is a huge ask and one that I certainly am not prepared to give.
People commented on the highly corroded state of the shaft presented and while a reasonable enough answer of the heat of combustion accelerating the corrosion process was given, this makes all the more remarkable that a plain blue paint mark managed to survive intact.
Still read the Official report as your faith in it may be considerable shaken. If it is, don't feel bad as you will not be the first to be so affected.
Don't forget that the report is a legal case for the prosecution as submitted to the UN for a judgement. IT is stunning that so much "evidence" discussed so prominently in the media during the release of the report does not actually make it into the report, not even as an exhibit and does not therefore actually form part of the official case.
Link 1:
"The metallic debris and chemical residue appear to be consistent with a type of torpedo made in Germany, indicating the North may have been trying to disguise its involvement by avoiding arms made by
allies China and Russia, Yonhap quoted the official as saying."
Ally russia!
, that says a lot about the credibility of the official, and also about the quoter when uncommented.
And note the formulation. It implies to some extend that it is already proven that North Korea is responsible, whereas in the previous paragraph "belief" is used. Spin control for newbies.
Link 3:
Yep, that oceanographic detail is really missing in the official report (among lots of other things).
However most of the arguments are, well, not convincing.
As stated above, the scratches may have been obtained after the split in two parts and the subsequent sinking.
The forward dented screw blades are convincing evidence for ground contact, while the hull is in backward motion and the screw is rotating. Not more, not less.
About the last statement of a collision. The damage of the 2 parts is clearly the type of damage from a shockwave & bubble effect, not a collision.
Link 4:
I found this link to be very unsatisfying. And the release of that document as a "report" is, well, not appropriate. If I would present something like that as a pupil in 7th grade, I d be ashamed.
So shame on bbc and the Joint... group and everyone else involved.
I used that presentation for reference after some search time:
Joint Civilian-Military Investigation Group Cheonan Presentation
As stated above the damage at the breaking point is certainly due to a shockwave & bubble effect as stated in the presentation/report.
Which leaves a torpedo or a mine.
The mine case is dismissed by the JIG for the following reasons:
Moored mine: unlikely
because of fast currents and no anchor found
Bottom mine: not possible because of depth of 47m
my 2cents:
Moored mine: unlikely is not impossible
Bottom mine: without seacharts provided and so on the statement of 47m is not verifyable and thus the "not possible" is subject to credible doubts
With the torpedo case the contact version can be rightfully ruled out, because it would not create the bubble effect.
Then comes an interesting part.
The analysis of hull damage is conducted, before the last open possibility is stated, the torpedo detonating somewhere beneath the ship.
For scientists thats a strange order. Because the damage obtained by such a torpedo can also be caused by a mine. So the analysis of hull damage, from a scientific perspective, has to be conducted before the mine & torpedo case, or after both, if one of them cant be rule out (unlikely is not impossible). Putting it in between indicates an agenda to drastically highlight one possiblity (aka spin control). That makes the whole paper very dubious.
It is also dubious, that the mine case is so easily dismissed, whereas the restrictions to the torpedo case are not mentioned at all.
Like Shallow water, angle of attack, precise positions, courses, position relative to the island, currents and all of that. Extremely dubious.
Then a lot of space is reserved for the linking of the torpedo to North Korea, but the linking of the torpedo to the incident is based on 2 statements.
1. The recovery of the torpedo parts.
2. The analysis of chemicals.
ad 1. Special net slide. Useless information concerning the recovery ships aso are an indicator of distraction. Long picture gallery from the recovery also such an indicator (only 2 pictures show the torp out of 6). Distraction from what?
No seacharts of the operations, no statement of neutral observers on board and so on.
ad 2. Nice graphs, but some questions remain.
Where were those chemicals found and what are the names of the neutral (non allied) observers involved?
Without the explicit involvement of neutral observers in those two critical links between the specific torpedo and the Cheonan, all that following linking of the torpedo to North Korea is utterly useless.
So what happend? I dont know!
All I know is:
1. There are scratches on the side of the Cheonan parts. And the screw blades are bent forward.
2. The breaking apart was caused by a shockwave and bubble effect, leaving a mine or a torpedo as a cause for it.
3. The overall credibility of the official report is extremely dubious because of very obvious spin control elements, like leaving out many important, certainly unclassified details, creating unsupported implications by stylistic tweaking aso.
