Research and Development Milestones	12 Months Ended
Research and Development Milestones	Dec. 31, 2013
Revenue Recognition [Abstract]
Research and Development Milestones	Research and Development Milestones Milestone payments. Milestone payments are recognized as revenue when milestones are deemed to be substantive and are achieved. A substantive milestone is one that is based on successful performance by the Company and not solely contingent upon the passage of time or performance by another party. Milestone payments collected in advance that have significant future performance obligations are presented as advance payments or deferred revenue, and are recognized when the milestone is achieved. As part of our ongoing participation in the B787-9 program, we received research and development milestone payments of $18.3 and $30.0 for the twelve months ended December 31, 2013 and December 31, 2012, respectively. Revenue and cost associated with the performance of the research and development are included in program revenue and costs. We expect to receive additional payments related to research and development on this program. These additional payments remain to be negotiated as of December 31, 2013.
