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.

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.

Tuesday is the deadline for all Boeing machinists to report back to work after their nearly two-month-long strike ended last week.
