The grappling hook thing is ridiculous. All you have to do to confirm that it is Apocryphal of the worst kind is listen to the music cue for this scene. The way it is composed fits the film perfectly--there is no break or edit anywhere that would indicate it had been trimmed to fit a shortened version of the scene. There are other places in the film where the music is edited to accommodate picture changes, and listening to them as compared to the score alone the cuts can be spotted easily enough, but the chasm scene never needed to be subjected to this.

One of the most intelligent answers that quashes the "grappling hook" myth once and for all. There is no place it would fit. John Williams writes the score to fit the emotions and pacing that is on the screen. There is no section prior to the grappling hook that would match a complete miss by luke. It never happened, it's just a false memory, same with people swearing they saw the anchorhead scenes in the movie at its release.
