The Milanese airship Italia reached the North Pole in 1928, but on the way back to base it encountered worsening weather and crashed to the ice. Ten men were thrown from the cabin; the chief engineer managed to throw them some supplies before he and five others were drawn helplessly away with the drifting envelope.
Nine of the castaways eventually reached civilization, but no trace of the airship or its captives has ever been found.
