Largest medieval 'super ship' longer than two school buses found

Archaeologists have discovered the largest-known medieval 'super ship', dating to the 1400s, near Copenhagen. It measures 28m long, 9m wide and 6m high, about the length of two school buses. The cargo ship would have carried about 300 tonnes of "everyday goods", including things like salt, timber, bricks or basic food items, researchers said.
