There has been a lot of talk here and elsewhere about how the Titanic's stern section imploded under the pressure of the sea as it sank. But how much evidence is really there that it did so? To my untrained eye, the way the bits and pieces from the stern of the ship are scattered about suggests that there might have also been an explosive effect, perhaps as it hit the bottom. This is the way I am looking at it. After the Titanic split into two and the bow sank beneath the surface of the Atlantic, the stern section remained afloat for a short time; I for one believe that this was for perhaps 40 to 50 seconds and not more. During that time, the sea would have been flooding the exposed deck spaces and would have continued to do so as the stern rose and then sank beneath the surface. As the rapid flooding continued, the air trapped in the as yet unflooded spaces at the very rear of the stern would have been compressed, even allowing for some of it being displaced and bubbled out through the open portholes etc. But the net effect would have been that the pressure differential between the sea outside and the inside of the flooding stern section would have been less than expected, thus delaying the implosive force. If that pressure differential remained not big enough to cause the expected implosion till the stern reached the ocean floor, could the eventual destructive effect have been an explosion due to the effect of the remaining compressed air?
