A method for modifying a target includes directing exhaust from multiple engines, preferably jet engines, towards the target. The target being modified can be, for example, a fire, an atmospheric system, a storm, snow, a gathering, a spill, an emission, a discharge, a mud slide, or a dust. The operation and/or deployment of the engines can be by remote control or robotics. In one example, a system for modifying a target includes a support for securing multiple jet engines and a fuel source. Preferably, the jet engines are mounted on turrets that are capable of being rotated.
