Safety concerns nix air show appearance for F-35 jet fighter

|By:, SA News Editor

The U.S. Defense Department says it will not send its advanced F-35 jet fighter to the U.K. for a long-awaited international debut because of lingering concerns about an engine fire that raised concerns about the safety of the next generation fighter jets.

While the military cleared the F-35 for limited flights earlier today, the Pentagon says the restrictions made it impossible to fly the plane to the U.K. to take part in the Farnborough airshow now under way.

The cancellation is a blow to the Pentagon's most expensive military program, as well as to Lockheed Martin (NYSE:LMT), which makes the F-35, and United Technologies (NYSE:UTX) unit Pratt Whitney, which makes the engines.
