        public abstract class Shuttle         {           public abstract double TWR();         }

2. Next, create a class called NasaShuttle and have it inherit from the abstract class Shuttle by putting the abstract class name after a colon at the end of the NasaShuttle class declaration:

        public class NasaShuttle : Shuttle         {         }

4. To fix the issues identified, type Ctrl + . (control key and period) and let Visual Studio show ...
