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.

Also in case you're wondering, the elevation at these airfields is around 4500 feet, which is high-ish; and the landing strips appear to be around 1000 - 1200 feet long, which is short. Impressive. (Photo at top of this post is from Dearden's site. And here is a sample dramatic entry from his Papuan flying adventures.)

A different pilot's video of landing on one of these airports is here.

3) World's shortest flight: runner up. It's from my ancestral homeland of Scotland, and it's about 90 seconds from takeoff to touchdown -- as you can see in the video of one entire flight, below. You'll note that about 40 seconds after takeoff the pilot is already reducing power to prepare for landing.

Compared with normal commercial journeys, this up-and-down flight path seems very odd -- but it's not that different from the routine training exercise of "flying the pattern" that all pilots have gone through. Pattern work involves taking off, climbing to 800 - 1000 feet above the ground, and doing a series of four right- or left-hand turns to make a rectangular path above the ground before coming in for landing again, a minute or so after takeoff. My point is simply that reducing power and speed very soon after lifting off is a familiar rather than an alien thing to do.
