There are some articles that argues that the Titanic suffered from a catastrophic fire below deck that made the hull brittle enough to sink when it hit the iceberg. The theory appears to have some traction as documentaries has been broadcasted on the Smithsonian channel in the USA as well as Channel 4 in the UK.
Documentaries are all well and good, but what is the opinion of our esteemed experts on AskHistorians? What does current research tell us?

Titanic: Fire and Ice (Or What You Will)
The people who wrote this article have written many other works that are held in high esteem in the Titanic community, so I hold their opinion over Molony's.
Basically, no.
Longer story, the "mark" is not near the coal bunker in question, other images of the same area on the same day don't have the same mark, images of Olympic have a similar effect, Molony misrepresented the data several times and the Titanic was doomed the moment she struck the iceberg based on her design alone.
