Boeing (NYSE:BA) and Airbus have been locked in a long-running battle for supremacy in the market for widebody aircraft.  With new airplane models like Boeing's 787 and Airbus' A350, both manufacturers have increased their use of lightweight composite materials to produce significant fuel-efficiency improvements.

At the Paris Air Show last month, Boeing announced a new, larger version of its popular 787 Dreamliner, with initial orders from several airlines including United Continental (NASDAQ:UAL).  The new plane -- dubbed the 787-10 -- attacks the Airbus A350's largest market segment.  Moreover, it is expected to offer better fuel efficiency than the comparable Airbus product.

Will this new version of the Dreamliner allow Boeing to eat Airbus' lunch? In the following video, Motley Fool industrials bureau chief Isaac Pino and Motley Fool contributor Adam Levine-Weinberg discuss the competition between Boeing and Airbus and the prospects for Boeing's new plane.
