FollowPath for non-Player Bot

I worked through the bot tutorials of Kevin Harris based on "tutorial.base" mod shipped with TGE and was abled to get the bots to work, follow a path and take damage from the rocket launcher. Then I started trying to get an aircraft non-player bot to fly a path in the same "tutorial.base" mod. I was able to get my bot to "spawnOnPath as far as the x & y axis but not z. My acircraft bot is partly below ground level whereas the path is above the ground a ways. (see screenshot below). Also, the aircraft bot just keeps going back and forth between 2 points not 4. I've also included part of the code from my file aircraft.cs and a modified bot.cs from "tutorial.base". Can anyone help, please!
