Drones are scary enough WITHOUT flame throwers. The TF-19 Flamethrower Drone is being marketed for industrial use. The company that created the product called Throwflame, says it's "a game changer for clearing vital infrastructure, igniting remote vegetation, and eliminating pests."
Yikes! Maybe a background check should be required to purchase one of these things. The WASP costs a whopping $1,500 — and that's without a drone. Add on the cost of a DJI S1000+ drone, which runs $1,500, and you're looking at $3,000 for the full setup.
