I have been asked by the lawyers if there are any games out there
that have used any one of the following features.  If you could provide me
with any information that would be appreciated.

     1. Player selectable Zoom.  I have seen a Sega sitdown that used a zoom 
	to move to and from the cockpit of a jet but it was not controllable.
	What is the name of this game?  Are there other games with a zoom?

     2. Terrain following shadows.  I believe the game Zaxxon and F-15 used 
	shadows to give the player a height.  Are there any others that 
	provided a shadow that followed the terrain?

     3.	Automatic ground avoidance.  I believe F-15 and others prevented the 
	player from flying into the ground (vertical avoidance).  Are there
	any other games like this?  Are there any games that detected terrain
	in front of the player and helped the player avoid that terrain in
	any way?
