Narrative:

Captured the glide slope from above in visual conditions. Had higher than normal sink rate and touchdown point appeared to be in the water about 1.5 miles out from runway. Left engaged to see what would happen; and took over manually at 800 ft. Would have made a big splash. Duplicated this again on same flight on the several days later.
