"The World Without Us"

A very detailed look at how long things last.

There was a book about this a few years ago: http://www.amazon.com/The-World-Without-Alan-Weisman/dp/0312...

I don't view their plan as pointless at all. Attempting to document an "average" airline passenger is an interesting social exercise I look forward to reading about. I've recently flown to Germany and Japan from the USA and met extraordinary people along the way.

Also, the added effect to our planet by having a plane that's going to fly regardless carry 2 additional people (plus the weight of their luggage) is minuscule at worst.

I suggest a reading of "The World Without Us" by Alan Weisman for a look at just how durable our planet is. (http://www.amazon.com/World-Without-Us-Alan-Weisman/dp/03124...)
