Alright....I'm new to this post so I will even things out here and explain to you WHY this is not a good idea.
First, how is this a good idea if no one wants it? The definition of a good idea is one everyone would like/enjoy, everyone has criticized it thus far, it is not a good idea, There is a large difference as to what is a good idea to you, and what in general is a good idea, Breathing, is a good idea, this everyone can agree on because everyone does it, however your idea of "flying in a cardboard box" is not a good idea because I'm sure very few people in the world even think of something this idiotic.
Next, If you posted this, you are saying "Please leave your suggestions/view here" Not, "alright it's here and someone has to do this", the forum works both ways, you can't post something and expect no one to criticize your way of thinking.
Lastly, It says something about a person's personality when they can't keep to the topic of their own post, like the one below, that is pathetic, I have heard of other leading the topic off course but not by their own creators, you are not very mature for your age otherwise you would have taken this flame like a champ and put up more intelligent reasons as to why your idea is good. As I have read in your topics, if you are older than twelve, I think you need to grow up, otherwise I suggest keeping quiet on the forums until then.
Note: In the last topic, I am not suggesting that all people below eleven years of age are immature. Just this person in particular.
