Thus, on Christmas day 1939, over two years before the publication of Flight to Arras, Longbottom issued a SECRET report titled "Condensation Trails at High Altitudes" which begins by explaining the major implication of contrails
for air warfare: a contrail
aids enemy defenders by betraying the position of an aircraft that might otherwise be invisible.
This is followed by a review of the major developments that made high altitude flight part of routine combat operations and led to the first recorded observation of contrails
in combat, this coming during the Spanish Civil War, Europe's dress rehearsal for World War II.
During the day, contrails
either can reflect heat back into space (the Albedo Effect) or trap heat below (the Greenhouse Effect).
But they all share a common element: They are true accounts, as told by Contrails
Researchers from NASA's Langley Research Center presented evidence that contrails
are contributing to global warming and causing local effects over areas with heavy air traffic.
And, what's more, Saturday's "failure" wasn't some obscure accident that will make Page 3; instead, the Columbia's contrail
streaked the Texas sky, like a skywriter's lament, for all to see.
The event will give journalists and social media users an opportunity to learn more about scientific research being conducted on the effects of alternate fuels, including synthetic and biofuel formulations, on engine performance, emissions and aircraft-generated contrails
at altitudes typically flown by commercial airliners.
In aeronautics, contrails
are better known as what?
Over a nondescript channel, white contrails
rear up like a wall.
Researchers said aircraft will be able to lessen their contributions to global warming by avoiding the places where the thinly shaped clouds contrails
The research found that aircraft contribute less to global warming by avoiding the places where the thinly shaped clouds, called contrails
, are produced by them even if that means flying further and emitting more carbon dioxide.
He claims that his meteorological credentials as a former Fleet Air Arm pilot led him to conclude that the overhead aerial phenomena we were then actually witnessing were simply jet aircraft contrails
