Flipping channels and stopped on how it's made. They just happened to be taking a bvm jet out of the mold.
The name of the episode is "Worcester sauce, lawn bowls, radio controlled model jets"

Seen that one, also the one at the Jet Cat factory
cool to see how the stuff we buy is made

Here's the segment.

That episode is over a year old.....

First aired 2010. Pretty cool though

Same as how $100 bills are made....
