Here is a nice trivia question:

What kills more people each year: plane crashes or plane exhaust?

A recent study published in Nature News (here) shows that “more people die each year from exposure to toxic pollutants in plane exhaust then in a plane crash” – by a factor of 1:10 in fact.

Well, this is old news really, but, what is indeed new is the discovery by experts that emissions above 3000 feet are responsible for most deaths. This may be attributed to the increase in coverage of flights at and above 3000 feet (that is, chances are that it is still very very bad to live next to an airport).
