Three India-bound Boeing 787 Dreamliners have been forced to return back to base within a 36-hour period after being hit with problems. The Air India passenger jets -the same type as the aircraft involved in last week's tragedy in Ahmedabad- suffered a mix of issues from a bomb threat to a technical glitch.

An Air India Boeing 787-8 flight headed for New Delhi returned to Hong Kong shortly after takeoff Monday because of a "technical issue," Indian media reported.
