I remember seeing AirTruks operating as a kid too, they'd drive the ground truck in between the tail booms and fill it up with fertilizer through a canvas funnel. And some of the airstrips they operated out of were truly hair-raising, more ski jumps carved out of the side of a hill with a D4 than anything else. For ugly aircraft, look up French pre-WWII military aircraft, things like the Amiot 143 (yes, that's a real aircraft, not an AI hallucination) or almost anything that Farman made, "let's put wings on an aviary!". I think the 143's main defense was that Bf110 pilots would be so distracted either boggling or laughing they'd forget to fire at it.
