I have been working with objects long enough to have the basics down,
but some things give me fits, and this is one of them.

Brief description:
I have an airplane object, and each airplane has an owner.
Likewise I have a customer object and each customer has a list of
airplanes.

The basic structure of my objects is: (ignoring public/private for
clarity)

public class Aircraft
{
   int ID;
   string Series;
   List<Aircraft_Options> OptionList;
   Customer Owner;

   /* Assorted Methods */...
}

public class Customer
{
   int ID;
   string Name;
   List<Aircraft> AircraftList;

   /* Assorted Methods */...
}

I want Aircraft to have the Customer object for reference when I grab
the Aircraft List, and obviously when I grab the Customer I want access
to all the associated aircraft. It seems to me I'll run into problems
with recursion. I considered a limited Customer class for Aircraft to
have, but that doesn't strike me as efficient.

How should I best deal with this situation?
