help on final fantasy 7

so, right now im on disc 2 i just finished the part where i end up escaping that city witht the big ass cannon via airship. through out the dialouge the characters where talking about how now we must save cloud as i talked to red he said to check the north crader for the life stream that there is also a small island that i can land on for the search, he also said the the life stream sometimes comes out via south island but i dont see shit. the only thing that i see is some big ord in the north crader that every time i get near it it pushes me back. i have been stuck at this part for 2 weeks now i i lost all hope untill i thought of asking for help here. i tried finding help on google but all those damn links dont help for shit!!! if you can tell me what to do i will love you forever and ill +rep you.

I can't remember the exact thing, but I'm very sure you can find the answer here.
