Perhaps there's a pocket of zero gravity at the top of the dome.
Look how many layers there are to the Earth, all the entire thing is from underground upwards is thin layers. There's not much of just one element.
Is it really impossible for the "sky" to be comprised of part gravity and part non-gravity? This could explain every last thing in the FET as far as how do they have satellites and how do they have NASA footage from 1969 showing them floating around in a craft.
Excuse me if all of this was covered already somewhere, tsk.
