GL: Hyper Mileing - Twin Engines

[Dave Friedrich]

John, auto pilots are thrown off by the magnetic attraction of metal  
bridges and other large metal objects. On the Erie, the bridges and  
locks are generally right together, and using the auto pilot then  
could have been more affected by the bridges than by how many engines  
you were using.
