There is no definitive answer to this question, as the development of flying cars is still in its early stages. However, some methods that could be used to get a flying car into Ff15 include:

  1. Invest in a company that specializes in the development and manufacture of flying cars. This will allow you to get a car that is specifically designed for use in Ff15.
  2. Use online resources to find information on how to build your own flying car. This will allow you to learn about the various steps involved in creating a working flying car, and also give you an idea of what costs and time may be involved.
  3. Attend an event related to the development of flying cars, such as the International Flying Car Symposium (IFCS). This event will provide an overview of current research and developments related to flying cars, as well as tips on how to build your own vehicle.
