- 1903 – Two American brothers, Orville and Wilbur Wright build an aircraft that can fly even though it is heavier than air. Their powered aircraft travels just 120 feet in 12 seconds, but it inspires engineers and inventors around the world by showing what is possible.

- 1909 – Cody continues to develop his aircraft design and on 14 May flies for over one mile. In August, he judges it safe enough to fly with a passenger. His wife, Elizabeth Mary King, becomes the first woman to fly in an aircraft in the United Kingdom.

- 1916 - On 23 September, a German airship bombed the East Coast and south of England, resulting in around 170 casualties.
