And I forgot, I also believe that they are spiritual in nature. I believe the truly awesome crafts are The LORD’s, and the lesser, poorer imitations are of the enemy.
It’s not that The LORD and His angels need to travel by crafts, but for some reason He chooses it to be so, so it is.
Psalm 68:17 The chariots of God are twenty thousand, even thousands of angels: the Lord is among them, as in Sinai, in the holy place.
Researcher Guy Malone does not believe that any of the current crop of craft and critters are on God's side. He allowed, in personal conversation with Qx that maybe he'd allow a less than 1% chance that maybe a tiny minority might be at some point in time.
Qx believes that God has chosen to use craft for His angels on occasion. And, we may see more of them in the END TIMES. However, the Biblical test is still crucial--do the critters believe that Christ came in the flesh, died in the flesh, arose the 3rd day? If not, consider the critter accursed.
Interestingly, I think it was Jesse Duplantis spoke of coming to himself exiting a 'gondola' sort of vehicle into Heaven. And that when he left Heaven, he again entered the same gondola sort of craft and came to himself on earth. IIRC, he had no memory or awareness of what the trip between was like.
