A discovery flight can be a great new experience or the beginning of a career in aviation. A discovery flight can go in two directions. Some people just want to experience the view and go along for the ride. This is the first time some people have ever been in an airplane.
For others this is the beginning of a deeper understanding in aviation. If you want to start understanding aerodynamics, take the controls, and be part of the flight crew, the discovery flight can be more involved.
