Hello everyone ! I started looking for information on the Flat Earth topic, and I have seen maps. According to the Flat Earth Theory, the flat earth is surrounded by Antartica, which is a mass of ice that surrounds the Earth.

You agree with me when I say that now, in 2014, we have planes that can go really far away (since a long time now actually).

What if a plane tried to go beyond this ice mass ? It must have an end. So what ? Does the plane just fall into the vacuum of space ? I need to know 

(Btw, don't flame me, I'm not trying to bother you guys. Just asking questions.)
