I recommend this article by T.M. Sell that explores the long line of miscalculations, particularly the purchase of McDonnell Douglas, by the once-venerated Boeing Co. The problems highlighted in the Crosscut article include a poor board; too much power to the number-crunchers; too much outsourcing of parts, particularly with the 787; and pressure from Wall Street to shift to short-term profitability and rising stock prices.
Read it and weep. I recently talked with a pilot and close observer of Boeing. He said Boeing needed to find a new CEO and also to have the courage to stop selling to international airlines that do not have rigorous pilot training.
As for the impact on Seattle if Boeing is really crippled, I wonder how well local planners are taking that into account. The local weather forecast is pretty cloudy: Boeing cutting back; Amazon in political danger both nationally and in Seattle; a real estate bubble in Seattle; and the decline of China trade. That’s a lot of flashing yellow lights!
