In "Caution: Clawed Frogs."

Huh?

In "Where's my aircar?"

Flight systems have evolved in a major fashion. And the SR-71 was in use for nearly 2 decades before its existance was revealed. Black triangles that people associate with UFOs are most likely highly developed aircraft. God knows what else Boeing skunkworks have under development. There are aircars and jetpacks, plus notice the advances in private spacecraft recently? What we basically lack are air traffic control systems run by AI or highly sophisticated computer systems, because human beings are not bright enough to fly without pranging. The technology is there, but the infrastructure isn't.

In "The Legend of Sasquatch Mountain "

I think the key phrase is 'heroic dose'. Take enough, and oh yes, it's visual. Acid these days is real weak compared to the proper stuff. Anyway, yeah, DMT. Electronic machine elves. Watch out for those guys.
