promised land and the airship.

[boys from the dwarf]

i have two questions.ive been replaying the game for 4 days now and have made it to the northern crater.(the visit near the start of disk 2 not the final battle on disk 3.)so is the northern crater the promised land? and also there is a quick video that shows rufus and hojo e.c.t on an airship which looks almost identical to the highwind(on the inside at least i havent seen the outside.is this the highwind or just that one that shoots weapons head off.
EDIT:ive discovered why the airship looks like high wind.because it is.(i kept on playing it until i discovered but i just need to be certain about my other question.
