Airship glitch

The Airship Glitch is a glitch in Final Fantasy VI that allows the player to use the airship early in the game, potentially as early as leaving Narshe and entering the overworld for the first time on the World of Balance.

In its simplest form, the glitch is triggered by first saving the game at whatever point in the game the player wants to access the airship, then playing through the game as normal without saving, until the player reaches the Floating Continent. Then the player must make their way through the Floating Continent until they're given a chance to return to the Blackjack, leave the Floating Continent, fly around with the Blackjack for a bit without landing, then return to the Floating Continent and trigger a Game Over. When the game resumes, the player will be returned to the point where they last saved, but with access to the airship.

Because the airship is acquired through glitching, its use comes with many limitations: For instance, depending on when the glitch is triggered, the player can only land the airship once before it becomes inaccessible again. For this reason it's recommended the player land near Zozo if they intend to complete the game, as it's close to where the player would first acquire the airship normally and the furthest point in the story where the game can be completed using the glitch. In addition, since triggering the glitch requires the player to play through the entire World of Balance up to the Floating Continent, it is very impractical (but possible) to perform without using emulators and savestates.

In spite of its limitations, the Airship Glitch can be used to cause numerous scripting errors, as skipping from Narshe to Zozo fails to trigger many in-game scripts - this allows the player to, for example, use certain temporary characters outside of areas where they were intended to be used, including Maduin, Banon and General Leo. This glitch can also be used to replace temporary characters with the Ten Moogles, not unlike the infamous Kutan glitch, or to replace Relm and Strago with Ghosts, whose ability 'Posess' can then be used outside of the Phatom Train sequence, where no enemies are programmed with invulnerability against it (even bosses, up to and including Kefka).
