Let's assume the following scenario - you have a comm failure on your way to a class D controlled airport (during operation hours). Let's assume that you have no flight following nor have you filed a flight plan, so no one really knows you're coming, and no other airports are close enough.
You approach the airport and join the pattern.
You get no light signal from the tower whatsoever.
What do you do?
