If you click go after a battle, and get engaged before the menu slides back up to where its supposed to be, you can click go again and skip a battle... Glitches FTW
Dont listen to fainaent, you have to glide to about 200 alt. then start to use your fuel at an angle that gives a slight increase in altitude in 1/3 parts. once you slow down a bit, use more fuel. then afterwards glide at an angle that gives a small amount of speed, then once you get close to the water even it out. you'll get it in no time
