Those who said that (including myself) were talking to Tyrannosaurus rex, that claimed in your thread that he could land everywhere with his launcher, including the Sun.
And I asked him to post it in a different thread if he did, but that's because you're the thread owner. You were not concerned by this, you can use your thread as you wish, but he should create his own thread if he wants to show his launcher.
Apart from that it's a nice performance
As is, it isn't a challenge though. I can move your thread to General discussion, but you can also choose to convert your thread into a challenge ("Reach the Sun" or whatever you want). As you did it, you have the right to do so.
