"Six turning, four burning!"
Talking about nomenclature, I always wondered why JATO (jet-assisted takeoff) systems were called that, when they are actually rockets. I found out today.
JATO was invented pre-WWII. At the time, jet propulsion wasn’t a “thing,” and turbine engines were something you typically used with a boiler! At the time, a “jet” was simply something that produced motive force by a concentrated stream of high-energy exhaust. It wasn’t until later in that jets referred to air-breathers, and rockets to designs that carried their own oxidizer.
