Boeing is in big trouble.

"The one issue that does give me pause, and about which I should want to know more, is the cracked windscreen, because that could indicate unusual stress in the airframe.

"Then you could be talking about a fundamental design flaw."

Dreamliner: will it live up to its name?

Google continues to ignore its customers and make enemies.

Some people have been experiencing problems while using Google Chrome.

Such problems include random crashing.

With a PE of more than 22, Google looks pricey for a company whose revenue growth may be plateauing. They have tons of money for new innovative projects. But then so did Microsoft, but that didn't do anything for the stock price over the last decade.

Boeing seems to have been more into globalization than quality control, outsourcing as much as possible of its manufacturing to cheap labor areas, and separating management from production by moving head office to Chicago, which doesn't inspire huge confidence in their quality control or engineering.

Now, I don't know the exact design and assembly methods but my experience of technology and manufacturing (and racing mx) tells me such a large carbon structure is going to be a problem. Each material has it's characteristics and often can't just be copied from another material design. Example, BSA made a copy of their successful steel MX'er frame in titanium and it cracked all over the place, as The Speedwell Gearcase Company, who actually made it for them, told them it would. In exactly the same places! They offered a Ti-design but BSA refused, it had to look like the rest of the BSA line. Ironically, the Ti-design translated into steel excellently! (Tried to get the blueprints to make some frames for my friends and I, but they wanted too much cash to buy the rights).

We know steel and alloys very well by now, but fibre-tech is still in it's infancy (it's actually the resin, or glue, or 'plastic', used, that is the product, the fibres are merely lightweight reinforcement and are quiet well understood by now).

I'd never buy a 'glass' boat to sail the high-seas with, I'd always use steel. Even steel has a half-life, the cold water alters the molecular-structure after 10-15 years - info from Jap engineer who designed 1st supertanker - to the degree a tanker can snap in half in a storm. But a small, welded, rigid, vessel, up to about 6,000 tons max, will last 50 years.

Boeing are lying cowboys. They refused to admit they had a problem with the hydraulics operating the elevators, which could stick in flight. Simply changing the oil twice as often as suggested cured it. Don't trust the Yanks, period: the F15 fighter crashed as the wiring-loom was an inch too short - to save money and weight - and high G's caused the connector to pull out, no fly-by-wire anymore, big bang. All European F15's had the loom locally modded, the Yanks refused to admit anything.

Moral: we know what to do, how to do it, but the bean-counters only look at the numbers ...and the bonus they get for increasing profits.
