If they were within the Earths atmosphere, inside the electro magnetic shield, then strictly speaking they never left earth, and so never "returned"

Actually, to orbit the Earth you'd have be to outside of the earths atmosphere, other wise the resistance from the air particles would slow down your craft, causing you to drift back down to the Earth. So they did leave the Earth, and they did return.
