Seems the DC-8 might not be their airplane of the future—after all. Boeing now actually had TWO airplanes—a smaller, shorter range one () and a bigger, longer range one (). Visit the National Academies Press online, the - Index of - NOAA.

Uthe. As part of the atmospheric effects of aviation program (AEAP) the DC-8 is scheduled to conduct atmospheric aerosol and gas chemistry and radiation measurements of subsonic aircraft contrails and cirrus clouds. A scanning lidar system is being developed for installation on the DC-8 to support and extend the domain of the AEAP measurements.
Contrails (/ ˈ k ɒ n t r eɪ l z /; short for "condensation trails") or vapour trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several miles above the Earth's surface.
Contrails are composed primarily of water, in the form of ice crystals. The combination of water vapor in aircraft engine exhaust and the Altitude: 7, to 12, m, (25, to 40, ft). DC-8 as it sampled contrails produced by commercial airliners and its own exhaust (Fig. 1b). These two sets of contrails are ideal for tracking because they are extensive and easily distinguishable from natural clouds.
The third case involves linear contrails produced by commercial aircraft over the east. contrails to cirrus clouds. Two unique contrails, a pair of figure eights and a NASA DC-8 oval, were tracked for more than 7 hours.
A cluster of contrails from commercial aircraft lasted over 17 hours. The figure eights produced a cirrus cloud having a maximum extent of 12, km2; the commercial cluster reached an area of ~35, km2. The. LASE  The Lidar Atmospheric Sensing Experiment (LASE) flew on board the NASA DC-8 aircraft as part of NAMMA, measuring vertical profiles of aerosol and water vapor, operating in.
In this work we present cirrus optical properties measured by an airborne lidar over Europe during the Midlatitude Cirrus experiment (ML-CIRRUS). Aircraft contrails and the cirrus clouds. Also note the three embedded aircraft contrails at an altitude of about 12km revealed by the strongly scattering streaks near the beginning of the period, and the cirrus cloud mammatta-like structures at cloud base from to UTC, which, as examined in more detail below, are not uncommon in deep cirrus clouds.
To complete this exciting research, NASA's DC-8 flying laboratory will deploy to Ramstein Air Force Base, Germany in mid-Jan. to meet DLR's Advanced Technology Aircraft.

() showed that air from a cabin air vent stayed within the aircraft boundary layer for at least 20 m downstream. The investigations by Vay et al.

The light source for the aerosol measurements is a Continuum Nd:YAG laser operating at 50 shots per second. The laser transmits approximately mJ at nm, mJ at nm, and mJ at nm.
