A group of firefighters battling a house fire in El Cajon rescued two of their own from under burning debris Tuesday morning. Heartland Fire & Rescue crews were called to a two-story structure fire in the 1300 block of Helix View Drive around 3 a.m. and discovered a home fully engulfed with flames reaching as high as 50-feet. As firefighters worked to extinguish the blaze, a burning section of the home collapsed trapping two of them. Both were quickly pulled out from under the rubble. One of the firefighters was treated and transported to a nearby hospital with unknown injuries. The condition of the second firefighter is unknown at this time. The homeowner told 10News that all family members were able to evacuate the burning home safely. The fire has since been extinguished but crews remain on scene.
