AHMEDABAD, India — The Air India plane crash this week was one of India’s worst aviation disasters, killing 241 people on board and several people on the ground. Indian authorities said Friday the investigation into the crash was underway and is expected to include experts from the plane’s maker Boeing and U.S. aviation regulators.

Air India flight AI171, a Boeing 787-8 carrying 242 people, crashed after taking off from Ahmedabad on its way to London.

As the investigation continued Friday into the horrific Air India Boeing 787 Dreamliner crash that killed at least 290 people, the sole survivor is doing well but is "psychologically disturbed."
