AMARILLO, Texas , June 14, 2006 (AP)

Textron Inc. and Boeing Co. will demonstrate two of their new MV-22 Osprey aircraft at British air shows next month, Textron said Wednesday.

The MV-22 is the newest generation of Osprey, a hybrid that takes off and lands like a helicopter but flies like a plane.

Osprey aircraft, which employs tilt-rotor technology, had a troubled history going back to 2000, when a titanium hydraulic line ruptured on board and caused the death of 23 Marines. After undergoing additional testing and review over the past several years, the Osprey is touted by commanders as having the ability to haul more troops and equipment than existing helicopters, and is taknig the place of aging Marine fleets.

The companies said U.S. Marines will fly two MV-22 Ospreys from North Carolina to the United Kingdom in July for the Royal International Air Tattoo and the Farnborough International Air Show.

Pilots from Bell Boeing, a strategic alliance between Textron's Bell Helicopter and Boeing, will fly the aircraft during the demonstrations.

The Marine Corps, which is slated to buy 360 MV-22s, wants to develop procedures for long-range, over-water flying of the aircraft, Textron said. The companies also hope the trip validates the aircraft's long-range fuel system capability and aerial refueling data.

Shares of Providence, R.I.-based Textron rose $1.36 to $83.87 in afternoon trading on the New York Stock Exchange. Chicago-based Boeing's jumped $4.12, or 5.4 percent, to $81.10, as it won a new plane order from Singapore Airlines and watched its rival, Airbus, struggle amid delivery delays for its newest jumbo jet.
