Unfortunatly you do seem to not only be immature but thick headed as well. Let me explain a few simple things to you 1st the trainner plane is capable of flying 50-70mph. That means that its going to travel across your school fields in a matter of seconds. 2nd there is this well known law called Murphy's law that states quite simply "Anything that can happen usually will happen"

Your immaturity and failure to listen to those of us with experience is putting your classmates at physical risk and exposing you and your parents to a considerable financial risk (think Law suit).
