An Air India Boeing 787-8 flight headed for New Delhi returned to Hong Kong shortly after takeoff Monday because of a "technical issue," Indian media reported.

Officials said they had found the cockpit voice recorder that may provide crucial clues about what caused the Air India flight to crash, killing at least 270 people.

The head of Boeing Commercial Airplanes, Stephanie Pope, met the chairman of Air India on Monday in India, two sources said, as the companies seek to find the cause of last week's fatal crash involving a Boeing 787 Dreamliner.

The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

Air India's Chairman N. Chandrasekaran on Monday told staff that last week's plane crash that killed at least 271 people should be a catalyst to build a safer airline, urging employees to stay resolute amid any criticism.

Boeing's CEO pulled out of the Paris Air Show following the Air India crash, which has set a somber mood for the aviation and defense event at Le Bourget.

As part of ongoing investigations, the plane’s black boxes are being analysed. A black box records flight data, and includes a cockpit voice recorder for pilot exchanges and cockpit sounds. It will also pick up engine sounds. Today (Monday 16th) it’s been reported the cockpit recordings have been found.
