A "super scooper" air tanker makes waters drops as firefighters battle a fast-moving California wildfire, so-called the "Colby Fire", in the hills of Glendora January 16, 2014. The wildfire, started accidentally by three campers, roared out of control in foothills above Los Angeles on Thursday, destroying at least two homes and forcing more than 1,000 residents to flee, fire and law enforcement officials said. The wind-whipped blaze erupted before dawn in the Angeles National Forest north of Glendora, about 40 miles east of downtown Los Angeles in the foothills of the San Gabriel Mountains.
