Take a ride on the two solid rocket boosters that launched STS 134 (Endeavor) into orbit. Again, Flat Earthoids will scream that this is a computer generated hoax, but I will leave that up to you to decide. Notice that at times you will see the Earth below, but only a portion of it. The rest of the Earth is hidden by its curvature. If it were truly flat, surely we would be able to see the rest of the Earth from this altitude.
