Good job getting to the bottom. You have more patience then I do :)

I tried doing this for about three hours. I managed to get about half way down until I remembered to pick up an overshield, somehow I forgot that! I had to use a second Warthog to push the first one through the opening. I did this on Legendary and with Sgt. Johnson in the passenger seat. And I used the original Halo PC version. I never did get to the bottom this time, but I'm going to try again later and see how it goes.
