Most people have had a similar experience...

e.g. Can't fly becuase of etc etc etc... Look at the Airplane, Start the engine...

Next thing you know your in the air without your instructor...

The only difference is how it ends... For me I got down safe 3 or 4 times but that was as much luck as it was bad luck that you hit the tree... I had also Solo'd by that stage...

I think the worse thing will be explaining to your instructor... [:@]
