- Surgical Tools | Medicine wont cure a broken leg, or remove a bullet from someone's rib cage. You find a stash of surgical utensils in the sky ship's sick bay, along with some sterilising liquids. Even without proper training in their use, anyone would prefer to use them to cut open someone else over a sharpened rock any day!

- Cannons | Your sky ship's armaments are intact, and so you salvage them. Big and clunky, they require ten strong men to haul, and wont be of much help in an offensive battle. However, they'd make a wonderful part of your peoples' defences, or an Ace up your sleeve in certain combat scenarios. 

These look good?
