I spied this video of the flamboyant Richard Quest explaining to CNN viewers at the time of the Boeing 787 update call this week.
Quest says Boeing has failed to learn the lessons from Airbus with its A380 and he thinks that the 787 will be just as delayed.
The reasons why the aircraft is having so many problems, he explains, is for two reasons:
1. Technology - "A vast amount of the fuselage and the wings are made of carbon fibre which is the first time such a plane has been made in this way."
2. The way Boeing is constructing the aircraft - Boeing usually builds its aircraft at its Everett facility in Seattle but it decided to "build different parts in separate parts of the world. But the reality is that they can't do it, they don't know how to do it."
Here's a link to CNN but you'll have to search manually (because there isn't a specific code for each item) for "Problems plague Dreamliner" found within the US section.
