The submersible Trieste traveled to the bottom of mariana trench
In World War I, the wood placed at the bottom of trenches was primarily used for flooring and to provide a stable, dry surface for soldiers. This wooden flooring, often made from planks or logs, helped prevent mud accumulation and reduced the risk of trench foot and other health issues related to wet conditions. Additionally, it offered some insulation from the cold ground. The use of wood was crucial for maintaining trench hygiene and comfort in the harsh conditions of the battlefield.
Jacque Piccard and Don Walsh were aboard the only manned submarine to ever reach the bottom in a sub named trieste.
