You can access the Sunken Gelnika in Part 2 of the original FFVII once you have obtained a submarine. The Gelnika is a crashed airplane containing some of the most powerful gear in Final Fantasy VII.
There follows a list of the gear you can pick up here.
Furthermore, if you first visit the Gelnika in Part 2 of the game rather than Part 3, you can fight Rude and Reno. You can steal a powerful Ziedrich armor from Rude and a rare Tough Ring accessory from Reno!
