Ground & body
A4, 2008
By analyzing the 2008 video footage, three sketches were made describing the relative motion between the IL-76MDK, ground, and me. Each page traces the relative motion between two of these three bodies. The fixed body-coordinate reference frame switches between the top and bottom sketch on each page.
