Regarding the Titanic and Hindenburg, those are huge Revelations. The Titanic contained numerous influential passengers, but among the wealthiest was Jack Astor of the Astor family. He died aboard the ship. Media reports of his death contradicted each other. It is possible that he was refused a place in a lifeboat. More digging will be needed to find out the people who were uh, comped a ticket on the Titanic.

Regarding the sinking itself, though, I am quite familiar with that already. The ship sank because it was turned the wrong way. Essentially, the aft of the ship was rotated toward the iceberg. In light of Q's revelations, this mistake may have been intentional.

As for the Hindenburg, none of the names of the dead really stand out to me. More digging needed.
