DALLAS (AP) -- A Boeing 787 jetliner on a test flight over Texas made an emergency landing Tuesday after smoke was detected in the main cabin, the latest setback in development of the new plane.

The plane landed safely in Laredo and the crew was evacuated, Boeing spokeswoman Loretta Gunter said. Boeing is still gathering information about the incident, she said.

The smoke appeared in the rear cabin of the plane, farthest from the cockpit, said Lynn Lunsford, a spokesman for the Federal Aviation Administration.

"The pilot landed and advised he was declaring an emergency," said Lunsford, who added that the airport fire department was called to the scene. He said the FAA would look into the incident.

Boeing said one person suffered a minor injury as the crew of 42 people were being evacuated down exit slides.
