Some questions I asked before:
1. If the ETs can be "out of phase" or cloaked in a way that they can't be attacked, why do they need security for a meeting?
2. When the cloaked ETs are standing at the beach, they don't move the sand. What are they standing on?
3. If the ETs are able to break or circumvent blocking measures, why can't they see where the death trap facilities are located?
@1. This reminds me of the documented sessions in Dr. Carl Wickland's book, Thirty Years Among the Dead, where his wife, the medium, had «channeled» some rather troublesome-beings every now and then; amongst the «dialogues» included expressions that sounded like «Oh, no, the authorities know where I am! I have to go now!» even though it was just Dr. Carl Wickland, his wife (Anna Wickland), and maybe one of their other rescue-worker or doctor-friends in the room (physically). We should remember that earth isn't populated by solely physical-beings.

@2. Why can't they stand on the sand without moving it? Would someone in an Astral-Projection/OBE move the sand when standing on it in a non-dense dimension ?
@3. Are you assuming that said facilities are physical-structures/devices ?
Standing on something means that there is a physical force applied, and regarding sand, that physical force is strong enough to move the sand particles. If they don't move the sand, there is no physical force, which means they are not standing on it.
And yes, I'm assuming that a structure is physical, because physical means to have form. Doesn't mean that the structure is physical in our plane of existence – but it is physical in its own plane, and thus can be seen.
