: I'm thinking that you could do without it in this alcove method though.

I could get the front of the Warthog through the opening but it wouldn't power all the way through. I used a second Warthog to shove the first one through the opening. Checkpoints are a problem with the original PC version but somehow a checkpoint triggered just after shoving the first Warthog through. The good thing about the PC version is I can save any checkpoint and replay it anytime I want. I'll revisit this again after the holidays.
