Book Description
Aircraft emissions lead to contrails and change cloud coverage in the upper troposphere/lower stratosphere, but their quantitative impact on climate is highly uncertain. As environmental policy turns toward regulating anthropogenic climate change components, it will be necessary to improve quantification of the climate impacts of aviation. Toward this end, we present two models of aircraft emissions. The first model is a large eddy simulation (LES) with three-dimensional, eddy-resolving flow physics and ice deposition/sublimation microphysics. Modeled ice properties, cloud optical depths, and contrail width growth rates are consistent with observational field studies. A series of sensitivity cases shows the effect of various parameters over twenty minutes of simulation time. The analysis focuses on properties such as contrail optical depth and cross-sectional width that are relevant to climate impacts. Vertical wind shear is found to have the strongest effect on these properties through the kinematic spreading of the contrail. In cases with no shear, optical depth is most sensitive to aircraft type and ambient humidity. One model parameter, the effective emission index of ice crystals, is also found to affect optical depth. A subset of the LES cases is run for two hours of simulation time to approach the scale of dynamical time steps modeled by global climate simulations. These cases use more realistic ice microphysics, including sedimentation, and forced ambient turbulence, both of which are processes that control contrail development at late times. The second model is a simple, low cost parameterization of aircraft plume dynamics, intended to be used as a subgrid plume model (SPM) within large scale atmospheric simulations. The SPM provides basic plume cross-section time advancement that has been used as a dilution model within a coupled global atmosphere-ocean climate simulation to study the effects of aviation on air quality and climate. Comparison to the twenty-minute and two-hour LES results demonstrates that the SPM captures important plume development characteristics under the effect of vertical shear and atmospheric turbulence.

Book Description
"Marrett takes readers into the cockpit as he "goes vertical" in a T-38 Talon, completes high-G maneuvers in an F-4C Phantom, and conducts wet-runway landing tests in the accident-prone F-111A Aardvark. He writes about Col. "Silver Fox" Stephens setting a world speed record in the YF-12 Blackbird and Bob Gilliland testing speed stalls in the SR-71 spy plane, but he also relives stories of crashes that killed test pilot friends. He recounts dead-sticking a T-38 to a landing on Rogers Dry Lake after a twin-engine failure and conducting dangerous tail hook barrier testing in a fighter jet without a canopy. A mysterious UFO sighting in the night sky above the Mojave Desert, known as "The Edwards Encounter" also receives Marrett's attention. Whether the author is assessing a new aircraft's performance or describing the experiences of test pilots as they routinely faced the possibility of death, this look at the golden age of flight testing both thrills and informs."--BOOK JACKET.

Book Description
This book details the actual accounts of 20 military aircraft crashes that occurred in the remote deserts and rugged highlands of Arizona. Each story looks into the events leading up to and after the crash, and describes what is left at the site today. These facts are corroborated by newly-declassified, old government documents, personal visits to the crash sites, and interviews with surviving crewman and families.

Book Description
How does a plane stay up in the air? Does the Mile-High Club actually exist? When you flush the toilet, where does it all go? Buckle up for some turbulence because nothing flies under the radar for Captain Jeremy Burfoot. With more than 35 years of airline experience, the former Qantas pilot presents an Airbus-load of stories about unruly passengers and cockpit clashes, and expertly navigates the bizarre myths surrounding everyday air travel. He explains important details like why plane wings actually bend, which in-flight surfaces carry the most germs and how to make plane food taste better. Jam-packed with hilarity, horror stories and honest insights, The Secret Life of Flying is part memoir and part guide to the skies - a razor-sharp and First Class read for anyone who has ever wondered who's really flying the plane ... PRAISE FOR THE SECRET LIFE OF FLYING 'A candid and entertaining behind the scenes view of aviation from former Qantas pilot, Captain Jeremy Burfoot.' Dick Smith, entrepreneur, bestselling author and aviator 'There is more to flying around the world than flaps, slats and airports. In this candid and no holds barred account of the intricacies of commercial aviation, Captain Burfoot deep dives into the technicalities and personalities surrounding your A to B flight. You will be chanting the checklists along with your pilots and smiling smugly wondering what colourful discussions are taking place behind the flight deck door. Fasten your seatbelt and prepare for take-off with Captain Burfoot and The Secret Life of Flying.' Captain Kevin Sullivan, former Qantas pilot and author of QF72 'Whether you're an aviation enthusiast or you just like reading success stories, Jeremy's life has been colourful, to say the least. At age 31 a Boeing 747 Captain! Few pilots travel through their career at this pace. The book is a must-read.' Mike Pero, entrepreneur and aviation enthusiast

Book Description
Get to know an American aviator who fought in the great air wars over Europe during World War II and steered a B-29 right through the center of a mushroom cloud from an atom bomb blast, among other aerial feats and accomplishments. From his youth during the Great Depression to his 22-year career in the U.S. Air Force to his life as a civilian and private pilot, Mr. Grey skillfully weaves together the events happening in the world with those occurring in his life. His voice is unique, his stories human and compelling. Readers will appreciate both his eloquence and candor. Vanishing Contrails is much more than just the recollections of a retired pilot. It speaks to the vanishing of an entire way of life and the code by which so many members of Mr. Grey's generation (the "greatest") lived their lives.
