Transcript for Yosemite Wildfire Increases in Size to 165 Square Miles
We do begin with that part of the great national park burning tonight. The wildfire racing into yosemite. Growing a a break neck pace and just look tonight, firefighters right there on the front linds, part of the forest up in flames tonight. Look at this, another view from the sky. The national guard lifting water from a nearby lake and dropping it from the air to dry to douse the flames. One more image of the scope tonight, a wall of smoke filling the sky and word this evening that that smoke now setting off a red alert for air quality. 150 miles away in reno. Our team is live inside the fire zone again tonight and abc's neal karlinsky leading us off. Reporter: A view of the air from above a fire that is now so big and so fast-moving veteran pilots are stunned by the sight. That is unreal. Reporter: From the cockpit, look closely, that speck is a spotter plane, it unleashes some smoke to mark the target, seconds later that's where pilots drop their flame retardant. Ready? Drop. Reporter: The land is torching with extreme fire behavior. You can clearly see trees ignite and be stwalyed up in second. The park, bigger than the statement of vermont is only being touched by fire on the west side right now. I got to know what people are. Reporter: We got up with hot spot fire teams concerned about conditions. You guys got to -- . If you guys pull out, I have to know. Absolutely. Your job is here is hold the line. Exactly. Are you surprised the behavior of this fire? Never seen a fire move this fast. In different directions. Reporter: Along the other front lines, homes with views of the fire burning straight at them. Teams of firefighters are actually sleeping here now. I just hope to god that it doesn't get past this point. I hope it doesn't burn any of these houses on this side. Reporter: Back out here live, this is an area the fire just burned through. You get a sense of the devastation. There are still hot spots here. The fire is burning on two fronts right now, one near yosemi yosemite, the other near homes and there's very little containment on either.
