Description	English: Orginal NASA Text: ACCESS Biofuels Flight Tests Puffy white exhaust contrails stream from the engines of NASA's DC-8 flying laboratory in this photo taken from an HU-25 Falcon flying in trail about 300 feet behind the DC-8. Instruments on the Falcon were measuring the chemical contents of the exhaust contrails at varying distances from the DC-8, which was using both standard JP8 jet fuel and a mix of JP-8 and a plant-derived biofuel. Deutsch: Kondesstreifen entstehen hinter einer DC-8 die JP-8 Treibstoff und ene Mischung aus JP-8 und Dioful verwendet. Die Aufnahme entstand während der Abgasmessung mit einem Messflugzeug.
