HMS Queen Elizabeth, set sail to the US where fighter jets will land on its flight deck for the first time.

During the 65,000-tonne carrier's trip it will embark two US F-35B test aircraft, based in Maryland.
They are expected to carry out 500 landings and take-offs during the carrier's 11 weeks at sea.
Capt Jerry Kyd, the carrier's commanding officer, added: "Crossing a major ocean with 1,500 sailors, aircrew and marines embarked and the spectre of the first F-35B Lightning landing on the deck in September is very exciting for us all."
On leaving Portsmouth, HMS Queen Elizabeth will carry out tests in UK waters before heading across the Atlantic to the US where it will also visit New York.
