Investigadores en India estudiaban las cajas negras de un Boeing 787 Dreamliner después de recuperarlas de los restos del avión

At least 270 died when the Air India flight crashed into the campus of a medical college in Ahmedabad shortly after takeoff on Thursday. Only one passenger among the 242 aboard survived.

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.

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.

Since Thursday evening, Mr Jignesh and his family have been doing the rounds of the Civil Hospital in Ahmedabad, trying to find details of his 22-year-old niece - one of the 242 passengers that died in an Air India plane crash earlier that day.

It could take months to fully understand what went wrong in the crash, the first involving a Dreamliner. Officials from India continued the investigation Friday.
