I listen to lots of truther radio....So I heard an interview with a long time Boeing Safety/Quality engineer was was let go (encouraged retirement) because of his complaints about the 737 and 787. He was saying that when they did the safety test on the 787's O2 masks only like 70%+ even dropped and around 50% had O2, the others didn't work. The higher ups didn'twant to hear about it and wouldn't fix it. There were a bunch of other safety problems they refused to address. He said the mindset of Boeing changed when they were bought by McDonald-Dougless and the higher ups were replaced. Suddenly the only thing that mattered was the stock price.
