The rules, as you gave them to us, didn't define an "airplane". So you have to go to a dictionary for that. Which means ball of paper isn't an airplane because an airplane has to have wings.

I understand why it felt unjust to you at the time. But even if you go 100% rules lawyer, the disqualification was correct.

Nope. Airplane was undefined as specific questions regarding design requirements and defining features where asked, the response was: there are no limitations other than it must be a shape made out of paper.
