There's a reason engineers are prissy about people coming along and saying "I write code, I'm an engineer" that people periodically try to sand-paper away.
Engineers don't just tie a sheet to a rock and throw it off a cliff and call themselves aerospace engineers.
They do full diligence on the theory, math, physics, material science, fluid dynamics, etc, and plan a controlled series of tests specifically designed to verify/challenge/disprove their concept and the theories behind it.
Sure, there's a team member ultimately responsible throwing half a dozen rocks off a cliff in the first test.
A technician.
The guy who throws the rock off the cliff is a technician.
