I'm sure the person who wrote this caption wasn't thinking of it this way, BUT:
That truck is stuck directly under the main fan blades of a high-bypass turbofan engine, which function essentially as a ducted propeller. They get rotated by a turbine in the jet exhaust and generate much more thrust than the escaping exhaust gasses themselves.
Propeller is a specific thing in aviation, and that doesnโt include turbofans. It does include turboprops, which is why they have โpropโ in the name, and not โfanโ.
