My hon. Friend is right to draw attention to the importance of the F-35 programme to businesses up and down this country, including in Gloucestershire. Last year, the F-35 suffered an engine incident, which is being investigated. It is absolutely right that the safety of aircrew and aircraft are of paramount importance, rather than seeking to attend air shows around the world. Obviously, we would welcome the F-35 once it has been declared safe, and we are still hopeful that it will arrive at Farnborough before the air show finishes.
