The Boeing 787 Dreamliner is several tons heavier than originally promised, according to the Los Angeles Times, but the company insists the plane will still meet targets for range, payload and fuel efficiency. Based on briefing documents sent to airlines before last week's test flight, "It's not unreasonable to assume that the operating empty weight is about 10,000 pounds heavier than what was originally on the drawing board," one aviation consultant said. Although Boeing won't disclose the weight of the plane, it says some numbers have been misinterpreted and that performance will not be affected. Improvements in aerodynamics and engine technology will make up for any added weight, according to a company official.
