^^Interesting. Ok, my uncle was a pilot in the Air Force in WWII and Korea, but I don't recall hearing him say it.
Maybe he said it when you were too little to remember and then as an adult you heard the instructor say something in the same vein and corrected it in your takeaway version?
I'm sorry for interrogating you about this, it's just so curious
