While an airport in Bhutan is the most extreme example -- only eight pilots in the world are qualified to fly into Paro -- a number of the world's airports, from St. Maarten in the Caribbean to Madeira Airport in Funchal, can present challenges for pilots. No wonder they've been known to say "Any landing you can walk away from is a good landing."
Today, sadly, air travel has become an awful, dignity-sucking ordeal as we are forced to stand in long lines without shoes on, subjected to pat downs and body scans. This all for the privilege of being crammed like sardines into a tin can where we might sit on the tarmac for hours, with nary a pretzel or cup of tap water in sight.
