While that does get slightly repetitive, it is a convention to the necessities of the modern TV audience, which is prone to channel flipping and coming in to the show at any point along the way. The repeats are used to draw in and update these itenerant viewers so they can perhaps get interested in the show.

My observation is that “plausible” has been used for everything from “we couldn’t outright disprove the possibility” to “we don’t know of a confirmed case, but given the right circumstances it could happen”. It seems to me they have self-limited by sticking to the three category rating system.

Actually, I’m not sure what Jamie’s training is, but most of them aren’t engineers, either. Okay, Grant has a Bachelor’s in Electrical Engineering. The rest are artists and craftsmen (craftspeople? craftspersons? craftisans?). Yeah, they know how to weld and how to build things, but don’t let the professional societies hear you call them engineers.

I can’t seriously believe that anyone who has spent much time launching and detonating things would have trouble with the concept.

To be fair, the biggest difficulty they had was designing a test set up to demonstrate the difference. They agreed with the concept, but it was the frustrating practical application that was the trick.

> “But hey, what about the penny that gets thrown off a building in a vertical position, avoiding the tumbling that slows it down? Will that put a dent in somebody’s skull?”

The key thing to realize is that all falling pennies will tumble. No matter how carefully you aim the penny to fall flat vertically, any air imbalance and the penny will tumble.
