Dornier Do X

The Dornier Do X was a three-storey flying boat built in 1929, then the largest aircraft in the world. Its twelve engines sat in pairs above the wing and were controlled by an engineer, who received instructions from the pilots through a ship-style engine telegraph. Inside were sleeping berths, a dining room and a lounge. On one demonstration flight it carried 169 people, including nine stowaways, setting a record that lasted twenty years. The Do X later flew from Germany to New York, though fires, repairs and repeated stops stretched the journey to nearly ten months. It crossed the Atlantic successfully, provided nobody was in a hurry.

Dodge Power Wagon

Dioscorea elephantipes

Dioscorea elephantipes is a South African yam that grows from an enormous, deeply fissured stem resembling an elephant’s foot or tortoise shell. From this armoured base emerges a slender vine with heart-shaped leaves, which disappears during the hot summer and returns in winter. One wild specimen was estimated to weigh 365 kilograms. It is essentially a delicate climbing plant attached to a small geological event.

Dyatlov Pass incident

The Dyatlov Pass incident refers to an event that resulted in the deaths of nine ski hikers in the northern Ural mountains on the night of February 2, 1959. The lack of eyewitnesses and subsequent investigations into the hikers' deaths have inspired much speculation. Investigators at the time determined that the hikers tore open their tent from within, departing barefoot in heavy snow. Though the corpses showed no signs of struggle, two victims had fractured skulls, two had broken ribs, and one was missing her tongue. According to sources, four of the victims' clothing contained substantial levels of radiation. There is no mention of this in contemporary documentation; it only appears in later documents. Soviet investigators determined only that "a compelling unknown force" had caused the deaths.
