In the linked information provided by Nutty.....there is a video purporting to be the instant the Moskva exploded.
The ship in the video (unless my old eyes deceive me....) is showing no signs of smoke or fire then suddenly does in fact suffer a tremendous explosion followed by large bits and pieces falling back to the sea.
If that is the Moskva and the explosion that ultimately sent it to the bottom....why no smoke, flame, or fire before the explosion.
It is daylight...not dark....and the missile attack was supposed to have occurred about 0130 local time.
