Watch the rear axle closely and you'll notice it pivots independently from the front wheels - this is a tiller ladder truck, a fire apparatus built in two connected sections like a giant articulated vehicle. A dedicated driver, called the tillerman, sits in a rear cab and steers the back axle by hand, letting a truck stretching 55–60 feet navigate turns that would be impossible for a single rigid chassis. It's a century-old engineering solution that's still the best way to get a full-length aerial ladder through narrow, tree-lined city streets - and it takes serious coordination between two drivers to pull off.
