Kansai (Osaka) Airport
There are the busiest airports rated either by passengers carried or number of movements (take off and landings). Then there's the largest airports according to acreage, smallest and the most challenging. Here's a great site sent in by Jack M, the "Strangest Airports."
I've been to a few of them and I was surprised to KIX (Kansai, Osaka, Japan) turned up first. I flew there at least 20 times. It's an engineering marvel. The terminal, propped up on hydraulic jacks, is adjusted now and again due to subsidence.
One other unique airport I've flown to as a passenger was Sable Island off the coast of Nova Scotia. Known as the "Graveyard of the Atlantic" it is home to numerous shipwrecks, aircraft and an oil rig. The island, about 22 miles long with it's widest point 3/4 mile, is a shifting sand bar. A Twin Islander lands on one of it's beaches. Home to wild horses from past shipwrecks it comes with many unique stories. I worked on the island for a month one university summer. It observes weather and is a launch site for upper air balloons under the identifier WSA and the airport (the island) is YSA.
Again Jack, thanks for sending along the site.
