1) Beware, Big Brother is watching you!
2) Try this:
with Helicopter; -- and other things that Main references
procedure Main is ...
This way, the compiler knows where to look for Helicopter etc., and
it knows for sure that when you reference it, it isn't a horrible
typing mistake that would otherwise compile.
Also, try to think of a better name for the program than "Main"!
