// Example of how one might do some object-oriented programming in 
// JavaScript. This example uses a prototype definition to present 
// a fictional application that might govern a plane taking off 
// from an airport.  Notice how the program is not just a list of 
// instructions - control often leaves the Plane object and then 
// later returns to the Plane upon some outside event or message.

// Initiates the take off process
Plane.prototype.takeOff = function() {
