1) What does this do?
    var myCars=["Saab","Volvo","BMW"];


2) Suppose a function says "var x".  Is x a local or a global variable?


3) Declare a boolean variable named 'd' that is true.


Make a web page that ...

4) When it loads, has an alert box that says "Don't use this for real flying!"

5) Has inputs that asks for the pilots weight, and the luggage weight.

6)  Computes the total weight and the moment 
    weight = pilots_weight+luggage_weight+1067
    moment = 35176+pilots_weight*39+luggage*64
    center_of_gravity = moment / weight

7) Warns if the total weight exceeds 1700, or the center of gravity is
not between 31.3 and 37.4
