VI's airships were the Blackjack and the Falcon. One of the ships in IV was also called the Falcon (I'm pretty sure it's the one the party aquires in the Tower of Babel.

Anyway, I definitly think Blackjack is the coolest. I'd love to have such a cool ship, and it would've been amazing if those games were actually playable. Plus having a shop, healer, and a guy to unequip the rest of your party was perfect.
