At the minimum, we can have some close-ups of the Epoch flying with the party on board (cf. the battle against Dalton Plus in CT), and some views taken from a farther distance, with the small Epoch sprite above an ocean tileset (the sprite which is seen under the Black Omen entrance in CT).
I'm fairly certain that we can find other creative ways to illustrate the sequence though. There's the mountain panorama tileset, we could depict the planes there with the "shiny star" sprites moving horizontally. We can also create sprites depicting small planes, seen laterally and/or from above. We might even be able to make a basic view of a city landscape seen from far-above, by graphic-hacking one of the unused tilesets. A lateral close-up of the Epoch, with the characters on it, is also possible (drawing this is not so difficult). An elaborated cutscene with a good music, and switching several times between at least 3 of these screens, will certainly achieve a nice effect.
...I'm sure we'll have fun coding or photoshopping all that (well, I at the least).
