It would have been a much tougher recovery with out the second truck loaded with a TC. I've tried heavy recoveries with a lighter vehicle before: Sometimes you can dig the wheels into pits so the winch does not drag the lighter vehicle into the ditch other times you can tie off your vehicle to another anchor point or vehicle and hope you don't damage yours at the front and rear. Those traction tracks were a great help in reducing the recovery angle to get back on the road - You can end up crabbing the the vehicle you want to recover and never get it back on the level if it is too steep. They were able to alter and reduce this angle by digging the high side and stacking the tracks on the low.
