Boeing and Airbus will show off rival aircraft at the Farnborough International Airshow, while vying for orders to supply passenger planes over the coming decades.
Boeing will present the new 787-9 Dreamliner passenger aircraft, along with the P-8A, a military derivative of the Boeing 737-800.
Airbus will display the world's largest passenger plane, the A380 superjumbo, as well as the extra-wide bodied A350 XWB.
There will also be an announcement at Farnborough this week of a list of eight possible locations across the UK for the first British spaceport, which is hoped to be opened by 2018.
