Dreamliner sleeps .....

A brand-new United Airlines "Dreamliner" airplane bound for Newark was diverted Tuesday morning, making an emergency landing in New Orleans because of an undisclosed mechanical problem.

The highly acclaimed Boeing 787 Dreamliner recently began service in North America in a debut last month with United Airlines. United and Boeing are both based in Chicago.

On Tuesday, the 7:30 a.m. United flight 1146 from Houston to Newark was diverted to Louis Armstrong New Orleans International Airport and landed safely there at 9:25 a.m., the airline said. The plane, the third delivered to United recently, carried 174 customers and 10 crew members. Neither United nor Boeing would describe the problem except to say it was a "mechanical issue."

"We are re-accommodating the customers on a different aircraft to Newark," United said in a statement. "United will work with Boeing to review the diversion and determine the cause."

The Federal Aviation Administration "is looking into it," an FAA spokesman said.

Pentagon restricts F-22 flights

By ROBERT BURNS

WASHINGTON (AP) — Facing a mysterious safety problem with the Air Force's most-prized stealth fighter, Defense Secretary Leon Panetta on Tuesday ordered new flight restrictions on the F-22 and summoned help from Navy and NASA experts.

Panetta endorsed Air Force efforts to figure out why some F-22 pilots have experienced dizziness and other symptoms of an oxygen shortage while flying, but his personal intervention signaled a new urgency. A secretary of defense does not normally get involved in a service-specific safety issue unless it is of great concern.

The Air Force grounded its F-22s for four months last year because of the oxygen-deficit problem, and now some pilots are refusing to fly them. An Air Force advisory panel headed by a retired Air Force general studied the problem for seven months and reported in March that it could not pinpoint the root cause. It endorsed a plan keeping the aircraft flying, however, with pilots using special sensors, filters and other safety precautions.

Panetta was briefed on the problem last Friday, just days after a CBS "60 Minutes" report featured two F-22 pilots who said that during some flights they and other pilots have experienced oxygen deprivation, disorientation and other problems. They cited safety concerns as well as the potential for long-term personal health issues.
