KUALA LUMPUR, Malaysia (AP) — A Malaysia Airlines Boeing 777-200 carrying 239 people lost contact over the South China Sea early Saturday morning on a flight from Kuala Lumpur to Beijing, and international aviation authorities still hadn't located the jetliner several hours later.

NEW YORK (AP) — A mystery man. A splashy reveal. A media frenzy. Newsweek staked its return from the dead on a story it knew would get attention. A cover story claiming it had uncovered "the face behind bitcoin," the world's most popular digital currency.

By Alwyn Scott and Tim Hepher NEW YORK (Reuters) - Boeing Co said on Friday that "hairline cracks" had been discovered in the wings of about 40 787 Dreamliners that are in production, marking another setback for the company's newest jet. The cracks have not been found on planes that are in use by airlines and therefore pose no safety risk, Boeing said, adding the problem also will not alter Boeing's plans to deliver 110 787s this year. However, Boeing said the cracks, which also occurred on the larger 787-9 model currently undergoing flight tests, could delay by a few weeks the date when airlines can take delivery of their new planes. The disclosure raised questions about repair costs and a possible minor increase in the weight of the plane, but did not seem to spell major trouble for Boeing, industry experts said.
