Ok, I'm going home and I already got two PM's! so, here is the cheat. I'm putting it in white, so those that don't wanna know don't have to read it. If you want read it, select the text as if you are going to copy it and it will show up for you.
Select from HERE:
To make the airplane go farther, drag the plane to the top left of the screen. Now drag it back as far left as you can - it will go off the screen a bit. Now, keep your mouse off the screen and come down about 2 inches or so. Now. Press the mouse button, and go down and to the right VERY fast. Let go of the mouse button right before you hit the red line. Do not re-enter the screen once you have your airplane floating up there in the top corner - if you do, then you'll pick the plane back up. Just move down to a little above mid-screen, then press the mouse button and go down and over really fast. Now, your plane is still sitting there - move the mouse back left really fast and watch it fly! Post your scores for us!
...to HERE for the tip!
I did this trick totally by accident. I have a wireless mouse and it "dropped" the plane and I couldn't get it back! I reckon it will work with a wired mouse too. Let me know.
