No, it's not because they're statically initialized. It's because fields 
are not polymorphic.

Either you can set the value in the constructor or turn "speed" in to a 
method/property. I think it's easiest to set it in the constructor:

class Airplane : Vehicle
{
     this()
     {
         speed = 100;
     }
}
