Take an aerial peek into an erupting volcano

Mexican experts conducted a flyover of the mighty Popocatepetl Volcano on Saturday to take a peek inside its flaming crater. Experts frequently monitor the blazing giant to gain insight into the intensity and timing of its eruptions. Popocatepetl is 5,426 meters tall and is the second-highest mountain in Mexico and the fifth-highest in North America. El Popo, as it is affectionately known locally, is one of Mexico's most active volcanoes.
