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.

Was the Boeing 787-8 Dreamliner that crashed over Ahmedabad seconds after taking off airworthy? When was it overhauled and maintained last time? Was there any issue with the engine? These questions are being asked the pilot sent the Mayday signals immediately after the plane could take off.
