AS many jets as Lion Air has wadded up the past 10-12 years, I'm astonished they can
even get insurance to operate... Can only imagine what their insurance bill is
I have asked the exact same question. When you consider how rare airliner accidents have become, the number that Lion has had is staggering.
Aviation safety is on a continuum. USA, Western Europe and Australia are at one one extreme. Average flight duration, terrain, weather, humidity, infrastructure, airports, approaches, technology, average age of crew, route variety, employment law, etc are factors.
You could probably also draw parallels for shipping and road accidents, compared with the USA and Indonesia.
