Sadly....as much as I wanted to, never saw anything unexplainable.
Oh, and TCAS would only come into play if the Zeta Reticulan ( >grin< ) spaceship had a transponder...especially if squawking Mode C....with all the attendant pitot-static instruments, too. LOL!
Now, the Vulcans?? Don't believe that "logical" exterior they like to project...deep down, those suppressed emotions, lurk some wicked senses of humor.....so, a few "false returns", wouldn't put it past them. Though, getting one to admit it is harder than prying the shell of an Arcturian she-crab....
