Boeing says it will be several weeks before it fully resumes building passenger planes, as factory workers return following a strike that lasted nearly two months. A Boeing spokesperson said Tuesday that the delay in restarting plants in Washington state and Oregon is due to multiple steps needed to resume production.

Boeing said Tuesday that it delivered 14 aircraft in October, but production will likely take several weeks to return to normal after a worker strike that hit operations at two major assembly plants.

As Boeing's Machinists return after eight weeks on strike, experts predict the work stoppage strained finances for the company and region, but likely ended before the cost got prohibitive.
