Re: plane.
There was an interesting piece on R4 whilst driving up yesterday.
It was about:
http://en.wikipedia.org/wiki/Bayesian_statistics
http://en.wikipedia.org/wiki/Bayesian_search_theory

Which was used to find an Air France downed plane, which was found, but the people involved described that as pure luck. In a search area which is " 'easier' due to the flatter sandier bottom" and a quarter of the size.... And that took 2 years.

Fast Co Labs have been running a very interesting series of articles breaking down ways of predicting where the plane might be if you're so inclined.
