While the WTS taught in 1926 that all "Bible Students" were going to heaven; they also taught that the people that were not going to heaven would be living forever on earth.
Like the ancient bible elders who were going to be resurrected back then and live in Beth Sarim? - yes, forgot about that. But they might as well have been in heaven if they were going to be able to fly like the angels. I guess they did not realize back then that comets are mostly ice and are not hot (of themselves) like the sun.
