You have to remember that Boeing has 5 Business Divisions and commercial aircraft is only one of them:
Commercial Aircraft

Integrated Defense Systems

Boeing Capital Corporation
https://www.boeing.com/bcc/
Phantom Works
https://www.boeing.com/phantom/
Shared Services Group
https://www.boeing.com/ssg/
Of these 5 official business units, only the Commercial Aircraft and the Integrated Defense Systems are "real" businesses that make money.
Boeing Capital Corporation basically figures how to get customer financing for their commercial aircraft sales, the Phantom Works is the Boeing R&D group and the Shared Services Group is exactly that, provides Corporate Administrative functions such as personnel, accounting, logistics and real estate.management, etc.
While on paper Boeing has a huge (>3,000) commercial plane backlog, in reality they are late on deliveries, partially due to strikes, and more significantly due to underestimating the complexity of manufacturing the 787 Dreamliner. Many 787 orders arose from canceled Airbus orders because of delayed deliveries, and now Boeing is starting to get 787 cancellations due to delayed deliveries. Furthermore the airlines are all loosing money after last year and many are looking for excuses to get out of their expensive purchase contracts, so the buisness unit is likely to have lower sales as more orders are canceled or pushed back.
Integrated Defense Systems design, build and maintain weapons systems, and provide personnel and logistical support for the government and government facilities. Weapon systems are expensive and with specification creep, are getting more expensive. Coupled with huge Federal budget shortfalls, it is likey that some of these weapon system procurements will be reduced in scope, delayed, spread out over a longer time period or simply eliminated, so this business unit is likey to have lower revenues as well.
The Boeing operating margins went negative in the Q4 2008, and they have a huge negative Q4 2008 cash flow of -$1.641 B compared to the good positive +$1.893B cash flow in Q4 2007, a stagering swing of -$3.53 B, and that's why Boeing has no choice but to lay-off 10,000 employees.
