My concern is the practicality of it. How long does it take to set up a drone? Unless there were dedicated vehicles that had the drones fueled and ready to launch from the top of the vehicle, hoses already attached and be instant starting, I don't see the practicality. If they were more quickly deployed than the time it takes to rig hoses and hoist ladders then I could see it but I'm not sure how feasible that would be.
