The video shows a large airplane flying through the sky, with a red substance being released from its underside. The substance appears to be a fire retardant, as it is being used to extinguish a wildfire. The airplane is flying over a mountainous area, and the red substance is being dropped onto the trees below. The sky is clear, and the airplane is flying at a high altitude. The red substance is creating a stark contrast against the greenery of the trees and the blue of the sky.
