Boeing.com has posted it will provide a final order count for 2015, will occur on January 7, 2016. Therefore, Winging It will publish its analysis following Boeing's final numbers are posted when they become available. Usually it has been my attempt by posting Winging It analysis at the close of a month or shortly after a month closes so the next summary should post about January 8, 2016, once Boeing shares its data with the public. So goes the blogging world.
