So You Want to Design a Jet Engine
 

A fascinating video by AgentJZ who has a very individual and captivating style. It clearly belongs here as he refers to many early engines and also mentions von Ohain and Whittle, while standing in front of an Orenda from an F-86.

I was already familiar with his videos, but ironically only found out about this one, via an email from a Kiwi friend.
