As the landing party had no experience of handling large rigid airships, Major EM Pritchard jumped by parachute and so became the first person to reach American soil by air from Europe. This was the first East-West crossing of the Atlantic and was done two weeks after the first transatlantic airplane flight. The return journey to England was from 10 to 13 July and took 75 hours) (Image)
