The car, van, fire truck and pushback tug were stacked boxes. The car is now an
operations SUV (rounded body, glass house with a sloped windscreen, roof light
bar, grille and lamps), the van a high-roof panel van, the fire truck an airport
crash tender with roof and bumper turrets on three axles, and the pushback a low
chamfered tug with a glazed cab. All stand on the ground at their built size.
Their trail anchors are measured again.

+  airport crash tender with turrets and the pushback a low tug with a glazed
+  cab, all on the ground at their built size (samehkhamis, #1730).
