You may recall from a previous post on my blog, that in the summer of 2014, the cabin crew on a flight from San Francisco to Hong Kong, grew concerned about disturbing graffiti on the tail of their Boeing 747. Drawn in the grease were two faces and the words "bye bye".
The airlines operations staff dismissed the drawing as a benign prank - not a security issue and tried to dispatch the plane. The cabin crew was less sanguine. Malaysia Flight 370 had disappeared without a trace just four months earlier justifying - to them at least - their edginess.
