I like to think of some tools in very specific ways...
Kerosene/Moonshine is a set of fuel tanks attached to a foot pump near the helm leading to the engines, as the pilot pumps on the pedal it sends the kero/moonshine into the engines, the engines then begin to work harder with the added strain on the nuts and bolts holding them in place, so the engineer must work on tightening those bolts to keep the engines in place and stop fuel leaks.
Claw is the foot pump again, but this time the pilot has turned the helm in the maximum turning for left or right, blocking fuel intake to one engine and pumping kerosene into the other, this cauases one engine to stall so the engines both require engineer attention.
Drogue chute, as above, the pilot loosens a rope either side and it increases wind resistance, may take a few seconds to get the side flaps back down.
Hydrogen forces the balloon pumps to work much harder often stretching the canvas, or causing the cogs in the balloons pumps to rattle and grind, engines attention.
Drogue vent, empties the balloon faster than normal, often leading to the balloon pump.coming loose or the balloon canvas needing engineer attention.
Impact bumpers, air bags which operate via a lever which moves pipes which fill the air bags but block exhausts, this being why the engines perform less effectively. The air bags being covered in armour to avoid being easily popped.
Tar, barrels of a potent mixture are left near the engines, at the pilots command the crew fill the engines with the tar (to avoid it clogging the fuel pumps kero or moonshine use.) once in the engines the tar spreads behind the ship, but its potency causes a lot of damage to its own engines.
