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

A Boeing Co. 787 Dreamliner aircraft operated by Air India that was bound for London crashed shortly after taking off in Ahmedabad, in what stands to be the worst accident involving the US planemaker’s most advanced widebody airliner.

As India makes a thorough sweep of its fleet, the United States has already made a decision on Boeing 787s in use around the country. Officials from the U.S. determined they have not seen any immediate safety data that would require halting Boeing 787 flights following the accident, according to Reuters .
