Hj  that is exactly the point  silence from pak navy would be interpreted by neutral people as meaning that they havent a clue to what happened to their submarine or they know but dont want to say what they know  as such we cannot find any info on Pakistans official position on the matter and it looks like they did not conduct an investigation  even Hamoodur Rahman commission did not get into this issue since their were no survivors  Since there is no official Pakistan version of events that is available in the interest of neutrality we need to remove the Pakistani version section which is based on speculation and biased sources if you can find a source that tells us what investigation was conducted by PN then that would be most useful    I
