[See update below.] The planning behind, and consequences of, China's expansion of its Air Defense Identification Zone, or ADIZ, in the East China Sea remain obscure. Of the various attempts to explain it, for now I like Robert Kelly's on Asian Security Blog best. It emphasizes the contradictory possibilities -- expansionism, miscalculation, domestic posturing -- that might all simultaneously be true. Previous coverage here, here, and here.
Related question: Should we worry that the U.S. government, having quickly taken a "this is bullshit!" stance by sending B-52s through the new ADIZ, is showing contradictions of its own, in urging U.S.-based airlines to file flight planes with the Chinese authorities?
No. This isn't the airlines' battle.* They already file flight plans for every operation with various national and international authorities. It's no harm to them to copy the Chinese in too. The immediate danger of this ADIZ is that it will be one more occasion for national-pride chest-bumping among Chinese and other (Japanese, U.S., South Korean, Taiwanese) military aircraft, in an already tense region where an accident or miscalculation could have big and dangerous consequences. It makes sense to minimize the chance that passenger airplanes could be involved.
And to be clear: this is a potentially very dangerous situation. The build-up to it has involved animus from many players, but this latest move is all China's doing.
Now let's look on the brighter side, all still in the aviation theme.
1) Private pilots' licenses come to China. Huzzah! This is one more step down the path I examined in China Airborne. That is, China's determination to will itself into leadership as an international aerospace power, despite its lack of (a) airports, (b) airplanes, (c) an advanced aircraft or engine-building industry, (d) flyable airspace, and (e) pilots. Everyone knows about its efforts to address the first three shortages -- or would, if they'd read my book! Last week I mentioned a long-awaited move on the airspace front: reducing the amount under the military's control. And yesterday we hear: easier requirements for certification as a pilot.
This is good news. Though anyone familiar with road traffic in China will pause for reflection on reading this quote, via the NYT:
On Friday, The Beijing News carried the headline: “In the future, getting a private pilot’s license will be just as easy as getting an automobile driver’s license.”
2) World's shortest commercial flight: the apparent champ. Via the very interesting site of Matt Dearden, a UK-born bush pilot working in Indonesia, this clip of a 73-second flight from one hilltop airstrip to another. Between the two airstrips is a very deep valley. The dramatic part of the video starts about 30 seconds in, with an approach to one of the tiny airstrips.
Passengers pay $5 apiece to save the many hours the steeply down-and-up-hill journey would take on foot. In case you're wondering, the locale of this flight is West Papua -- which is on the western, Indonesian half of the island whose eastern half is the nation of Papua New Guinea.
