I read (and can't recall the source) that, when they tested this system, they first tried it on a pig. But the pig couldn't use arms and legs to stabilize itself, and so it spun while being winched into the plane. It entered the plane in a disoriented state. When it recovered (?) from that, it attacked the crew.

Good times... ;-)

From https://www.cia.gov/library/center-for-the-study-of-intellig... : Lifted off the ground, the pig began to spin as it flew through the air at 125 mph. It arrived on board undamaged but in a disoriented state. Once it recovered, it attacked the crew.

Yes, that was it.

Personally this article turned out to be more interesting for me than the original post. I've seriously thought that it existed only as a movie effect and not in real life.
