* Fill and wear your camelpack. Ice Cold Water doesn't work with it, but the normal stuff does and will save a lot of effort.
* Get the wood for Tinker's Construct pattern, tool table, stencil table, and part builder, and make a bone mattock as soon as possible.
* Block off the engine spill. Not only is it directly dangerous, but the first creeper to walk into it will Ruin Your Day.
* Break the dark glass inside the ship, and use it to make a 2x3 'ceiling' outside the ship's caution-marked exit hatch, and make two 1x2 columns on each side of the door. Even if you can't make a ditch or a door in time, you can plant dust into the remaining gap overnight to make a safe spot.
* Start digging a two-deep and two-wide ditch around the caution-marked hatch exit. Might not finish this before the night starts, so head back in if it takes too long. Eventually will want to move this to three-deep.
* Shears will save your day.
* Build underground.
* Survivalist Generators help a lot, especially on the easy path.
