Boeing and European arch rival Airbus have racked up billions of dollars worth of aircraft sales at the Farnborough International Air Show in Britain. It's raised hopes that the aviation industry is taking off once again from the bottom of a two-year downturn.
After numerous delays Boeing's Dreamaker finally makes its international debut.
It's the star attraction at the Farnborough air show near London.
U.S. owned Boeing and its rival Airbus - owned by Europe's EADS - are both wooing customers with new aircraft.
Airbus's top attraction was its A400M military transport plane - another long-awaited design.
Both are made from a new light-weight carbon composite instead of the usual aluminum.
Boeing's chief pilot says the new material makes economic - and environmental - sense.
Mike Carriker, chief test pilot of Boeing 787 Dreamliner, said, "Green in the sense that we burn a lot less fuel per nautical mile for carrying the passengers, so if you burn less fuel you have less emissions.
The Dreamliner is two years behind schedule but Boeing's marketing Vice President is confident it will be a commercial success.
Randy Tinseth,vice president pf Boeing, marketing, said, "This airplane has been a great commercial success. Since we launched the airplane in 2004 we now stand with about 860 orders from more than 50 customers. Really unmatched success for the launch of any airplane at any time."
Within hours of the show opening - the first deals were being done.
Dubai's Emirates Airline placed an order for 30 Boeing 777 passenger jets - worth $9 billion dollars.
Good news - but some industry analysts were warning of turbulence ahead.
Howard Wheeldon, senior strategist of BGC Partners, said, "I think the mood in terms of commercial aerospace industry it is definitely better, there is some degree of recovery there but we mustn't get too euphoric there are lot's of problems ahead. The defense industry which is one half of this show as well I'm afraid it's gloom and doom."
Many European governments desperate to cut spending are looking closely at defense budgets.
Britain is already pushing through a comprehensive review of its military budgets and it's not alone.
Other European governments and the U.S. - one of the world's biggest spenders - are also expected to pull in the reins.
