COFFEE, TEA OR CHI? Hong Kong Airlines, a young regional air carrier in Asia, is training its newly-hired flight attendants in kung fu's Wing Chun style, a style well-suited to self-defense in tight places. The martial-arts training also is part of Hong Kong Airlines' marketing campaign in advance of its expected initial public offering next year. The publicity stunt worked, catching the eyes of the Wall Street Journal, MSNBC, the Economist and this low-rent blogger. Jet Li they ain't, but a few fighting techniques are better than none, I guess.
