MH370 had left Kuala Lumpur International Airport at 12.41 a.m. on March 8, 2014. The plane was en route to Beijing Capital International Airport, where it was expected to touch down at 6:30 a.m. after a journey of around 2,700 miles. And as the weather at take-off was fine, it may have seemed likely at first that the flight would be a smooth one.
