The deadly crash of Air India Flight 171 last week has centered renewed scrutiny on the airplane's manufacturer, Boeing. This time it's the 787 Dreamliner in investigators' sights. The accident, which killed over 270 people, was the first fatal crash for the Dreamliner since the model began flying in 2011.

An Air India pilot turned back his Delhi-bound Boeing 787-8 Dreamliner to Hong Kong airport as a precaution shortly after taking off on Monday, citing a technical issue, Indian media reported. Flight tracking data showed the pilot turning Flight AI315 around less than 30 minutes into the flight from Hong Kong.
