Oh it is part of a failed invasion alright
The greys are still trapped there, one of them managed to get access to a "smart"*- phone and used it to hack this, crack that and utilise the backdoor of the other to get access to the drone.
Now, the drone will only work for Abrahamic masters, being part of the Zionist machine, so its complex nanobot worm-code logic bomb security devices caused it to self-destruct, except that its powerful nuclear self destruct mechanism was subverted by the greys.
This led to the inevitable crash. The "Smart"-phone owner was killed and replaced by a terminator and the grey is even now being electro-schlocked as punishment.
Everytime you use a computer, thank the greys whose technology we stole.
The truth is out there (it's certainly not in this comment anyway).
I wanted to use black helicopter, alien, terminator and big brother icons, but I can only choose one. Xenu, I choose you! (The greys are Scientologists too)
*Oh the hubris of humanity.
