I watched the documentary last year regarding the fire in the coal bunker, it wasn’t a conspiracy theory, but after having seen the damage to the paint work on photos taken in Belfast the evidence was eventually found in historical documents from the time, coal can self ignite if it’s stacked high, they had to go fast across the Atlantic because the only way to get rid of the burning coal was to get it in the boilers ASAP, it couldn’t be replaced as there was a miners strike at the time, the high speed was also because whilst getting rid of the coal, they couldn’t afford to run out part way across the Atlantic as this would have been a major embarrassment in a cut throat industry, also the stokers who survived started to talk, White Star line got them on the first available boat back to Blighty to shut them up, the bulkhead where the fire was, was badly weakened by the heat, as well as being made of inferior quality steel, so under the pressure of the water as Titanic started to sink gave way, all this was made worse by the pressure to get across the Atlantic quickly as White Star Line were in financial difficulties, no conspiracy, just a perfect storm of lots of things going wrong that ended in disaster.
