Duck under and to the right of the first bubble, and then around the next to the wooden box next to the wrecked red bus, you can climb onto the box, and duck/lower duck/jump through the window (takes a little fiddling) and go out the open door on the left side of the bus and your free and clear of the bubbles.
I have tried and tried and tried to get into the bus from the box...its not working..is there something else missing?

No, you just have to fiddle switching between duck, lower duck and jump.
It's a pain I know, I was almost convinced there had to be another way through when I got it.
Thanks finally got through it..talk about a pain..now am at the part of the game on the heat pipes and have to chase some guy down through telaports..got over to him but everytime he gets away..even when trying to shoot him with the gun they tell me to use..
