    Cold War Hangar Navigating & Tales from On-board Shuttle
    From: R William McAllister
    Date: 2020 Jan 26, 10:47 -0800

    Presently I'm on my way to Oskosh, WI for an EAA welding workshop this weekend.  When I return home I'll post something on a far greater than 320 degree Heading Alignment Cone (HAC) that was a facinating artifact of great circle and HAC tangent intercept geometry that if not corrected would lead to problematic energy management for the Shuttle entry afflicted with it.
