I still can't understand how Boeing manages to have its stock value getting on for double what it was five years ago. We have had the 737 two-year grounding, now the 787 new deliveries grounding, the 747-8 programme abandoned with few sales, the 777X pushed back by years, all the potential law cases - where on earth are they getting the shareholders' money from. It's no wonder Wall Street thinks there's no real issue if the stock value does this.
