An aerial spray system can be attached to the undersurface of a helicopter for spraying ground level targets while the helicopter is hovering or in level flight. A television camera can be located in near proximity to the spray nozzles for electronically delivering a picture of the ground level condition to a television monitor in the helicopter, such that the technician is better enabled to aim the spray nozzles or target a specific ground level area. The aerial system can be used for riot control, or crop spraying, or forest fire containment.
