August 2014 investigation[edit]
In August 2014, two pilots were suspended after a plane carrying 280 passengers dropped 5000 feet. Indian air regulators issued an investigation on the situation. The plane was en route from Mumbai to Brussels. The captain was in "controlled rest" which is permitted under aviation laws. The co-pilot, responsible for the flying the aircraft while the captain was sleeping, "claims she was busy on her iPad and didn't notice the plane had lost altitude."[76]
