I co-ordinated an around the world event a few years back called ATIWED (Around The World In Eighty Days), downfall was that although a lot of organisation went into it, not that many participated
I'm quite keen on a dangerous airports event - just happen to be watching a documentary put out on the History Channel covering these types of airports.
Check out this youtube vid - Dash-6 landing at Talcha Airport in Nepal - looks like fun
