The equations all look good on first examination, but I started to evaluate the rotational theory from scratch, and as I had originally deduced I came up with almost one full rotation, actually .89 of a rotation after 1000 feet, however, the real focus in relation to the issue is that he was in sand that I quote was in soft deep sand sugar 8-10 inches deep, so all the calculations in the world only work on pavement which could maintain a controlled environment for each axle and hence tire,but there is a very forgiving nature to sand in which traction doesn't apply, hold on........let me hit that...damn......that is good..........now what was I saying?.....................oh yeah.......it will probably never happen again
