Last post for today. commercial space flights

If you were to go on a commercial space flight (which you can do today) and you saw that the earth was round, would you become a REer, or is there an explanation?

First I wouldn't go on a commercial program, nor do I think it likely that it would be available to me.

Assuming, however, that I actually saw such a sight with my own eyes in a convincing fashion, I would probably be open to the idea of a round earth.
