AHMEDABAD, India >> The investigation into the Air India plane crash that killed more than 240 people is focusing on the engine, flaps and landing gear, a source said on Friday, as the aviation regulator ordered safety checks on the airline’s entire Boeing-787 fleet.

A couple who were killed in the Air India crash were the "foundation of our family", their granddaughters have said. All but one of the 242 people on board the London Gatwick-bound aircraft died when it crashed into a residential area in Ahmedabad, western India, shortly after take-off on Thursday.
