Other Assets [Abstract]
Other Assets	Other Assets Sea Launch At March 31, 2018 and December 31, 2017, Other assets included $295 and $356 of receivables related to our former investment in the Sea Launch venture which became payable by certain Sea Launch partners following Sea Launch’s bankruptcy filing in June 2009. At March 31, 2018, the net amounts owed to Boeing by each of the partners were as follows: S.P. Koroley Rocket and Space Corporation Energia of Russia (RSC Energia) – $162, PO Yuzhnoye Mashinostroitelny Zavod of Ukraine – $89 and KB Yuzhnoye of Ukraine – $44. In 2013, we filed an action in the United States District Court for the Central District of California seeking reimbursement from the other Sea Launch partners. In 2016, the United States District Court for the Central District of California issued a judgment in favor of Boeing. Later that year, we reached an agreement which we believe will enable us to recover the outstanding receivable balance from RSC Energia over the next several years. We continue to pursue collection efforts against the former Ukrainian partners in connection with the court judgment. We continue to believe the partners have the financial wherewithal to pay and intend to pursue vigorously all of our rights and remedies. In the event we are unable to secure reimbursement from RSC Energia and the Ukrainian Sea Launch partners, we could incur additional charges. Spirit AeroSystems As of March 31, 2018 and December 31, 2017, Other assets included $137 of receivables related to indemnifications from Spirit AeroSystems, Inc. (Spirit) for costs incurred related to pension and retiree medical obligations of former Boeing employees who were subsequently employed by Spirit. During the fourth quarter of 2014, Boeing filed a complaint against Spirit in the Delaware Superior Court seeking to enforce our rights to indemnification and to recover from Spirit amounts incurred by Boeing for pension and retiree medical obligations. During 2017, the court ruled against Boeing and denied our claim. In January 2018, Boeing filed a notice of appeal with the Delaware Supreme Court. We believe we have substantial arguments on appeal and expect to fully recover from Spirit.
