If you are trying to complete this week's challenge, one of the objectives you will need to complete is to survive a dangerous encounter - you will also need to do this in either a boat or a plane.
But before you should be worried about buying either vehicle, you will first need to learn how to swim. To learn how to swim, you will need to age to the point where you are both 13 and in middle school.
Once you are in middle school, you will need to try out to the swim team and successfully join the club. Doing so will give your character the ability to swim, and after that, you will need to buy either a boat or a plane.
However, before you can buy either vehicle, you will need a license, and getting one is easy. For the boating license, all you need to do is find the option to get one under the license tab and pass the test.
But, for planes, you will need to get a pilot license, and before you can take the test to get it, you will need to have a total of 40 hours of practice flights under your belt.
You can take practice flights by simply attempting to take the test under the license tab and clicking yes on the prompt that shows up afterward. Do this four times, and you will be able to take and pass the pilot test.
Once you pass both tests or one of them, you buy either a boat or plane under the go shopping tab. When you get either a plane or boat purchased, you will need to take them out until you encounter an accident.
To do this for boats, simply click on your boat under assets and click the option that says ride, and for planes, you will need to hit the option that says fly.
Keep using the ride or fly option until you encounter an accident, and when you do, you will have a high chance of surviving since you know how to swim.
