An investigation into flight MH370's disappearance one year ago has found no red flags related to the crew or mechanical issues, according to an interim report released Sunday that shed no new light on the mystery.
"There were no behavioural signs of social isolation, change in habits or interest, self-neglect, drug or alcohol abuse of the Captain, First Officer and the Cabin Crew," said the report.
The report also ticked through a number of the plane's mechanical systems and noted in each case that according to available data and maintenance records, nothing alarming was seen.
