ER-2S

NASA brought over its Lockheed ER-2S research aircraft to the islands for oceanic and volcanic research flights. It was photographed above as it taxied out for take-off on two-and-a-half hour flight from Marine Corps Base Hawai‘i. HNL RareBirds was on-hand to capture the pre-flight, take-off, arrival, and post-flight of the ER-2S. If this aircraft looks like a US Air Force U-2S reconnaissance aircraft, that's because it was loaned to NASA, and converted for environmental research.
