In the video, a large airplane is flying over a mountainous area with a red substance trailing behind it. The substance appears to be a fire retardant, which is being dropped onto the mountainside to extinguish a fire. The airplane is flying at a low altitude, and the red substance is creating a stark contrast against the natural landscape. The mountainside is covered in smoke and flames, indicating that the fire is active and spreading. The airplane is the only visible object in the sky, and it is flying in a straight line over the affected area. The video does not contain any visible text or subtitles.
