Question: Who co-wrote a memoir with an American retired airline captain celebrated for the January 15, 2009 water landing of US Airways Flight 1549?
Context: US Airways Group Inc. was an airline holding company based in Tempe, Arizona.  US Airways Group operated US Airways, along with its subsidiaries PSA Airlines, Inc. and Piedmont Airlines, Inc., which are wholly owned but marketed under the branding of US Airways Express.  It merged with America West Holdings Corporation, parent of America West Airlines, in 2005, and the combined company adopted the better-known US Airways name; the two airlines' operating certificates merged in 2007.  It also operates additional companies that provide associated services.  ACE Aviation Holdings, the Canadian parent of Air Canada retained a roughly 6.1% investment stake in US Airways Group.  The route network covered destinations in 47 states, as well as international destinations. US Airways Express was the brand name for the regional affiliate of US Airways, under which a number of individually owned commuter air carriers and regional airlines operate short and medium haul routes.  This code sharing service was previously operated as USAir Express.  Mainline carriers often outsource to regional airlines to operate services in order to increase frequency, serve routes that would not sustain larger aircraft, or for other competitive reasons.  US Airways Express operations were conducted from smaller markets in the United States, Canada, and the Bahamas primarily centered on US Airways' major hubs and focus cities.  Upon the completion of US Airways' merger process with American Airlines, US Airways Express was rebranded as American Eagle on October 17, 2015. US Airways (formerly known as USAir) was a major American airline that ceased to operate independently when the Federal Aviation Administration granted a single operating certificate (SOC) for US Airways and American Airlines on April 8, 2015.  Publicly, the two carriers appeared to merge when their reservations systems and booking processes were merged on October 17, 2015; however, other systems were still separate at that time.  The airline had an extensive international and domestic network, with 193 destinations in 24 countries in North America, South America, Europe and the Middle East.  The airline was a member of the Star Alliance, before becoming an affiliate member of Oneworld in March 2014.  US Airways utilized a fleet of 343 mainline jet aircraft, as well as 278 regional jet and turbo-prop aircraft operated by contract and subsidiary airlines under the name US Airways Express via code sharing agreements. Sully (also known as Sully: Miracle on the Hudson) is a 2016 American biographical drama film directed by Clint Eastwood and written by Todd Komarnicki, based on the autobiography "" by Chesley Sullenberger and Jeffrey Zaslow.  The film stars Tom Hanks as Sullenberger, with Aaron Eckhart, Laura Linney, Anna Gunn, Autumn Reeser, Holt McCallany, Jamey Sheridan, and Jerry Ferrara in supporting roles.  The film follows Sullenberger's January 2009 emergency landing of US Airways Flight 1549 on the Hudson River, in which all 155 passengers and crew survived with only minor injuries, and the subsequent publicity and investigation. The US Airline Pilots Association (USAPA) was the collective bargaining agent for the majority former US Airways "East" pilots, and the minority former America West Airlines "West" pilots.  USAPA bullied its West pilots, and violated its duty to fairly represent them.  USAPA was led by East pilot Mike Cleary.  USAPA was formed by East pilots for the exclusive and immoral - if not illegal - purpose of attempting to renege upon the results of a binding arbitration into which the East pilots had previously entered with the West pilots.  After USAPA's dissolution, a number of East activists withheld millions of dollars from the entire membership.  During the fair representation trial, USAPA used as courtroom witnesses East pilots Sully Sullenberger and Jeffrey Skiles of the infamous Hudson River flight 1549.  Both witnesses testified in support of the discriminatory practices of USAPA, and why they felt justified in bullying, and attempting to break their arbitrated agreement with the innocent West pilots. US Airways Flight 1549 was an Airbus A320-214 which, three minutes after takeoff from New York City's LaGuardia Airport on January 15, 2009, struck a flock of Canada geese just northeast of the George Washington Bridge and consequently lost all engine power.  Unable to reach any airport, pilots Chesley Sullenberger and Jeffrey Skiles glided the plane to a ditching in the Hudson River off Midtown Manhattan.  All 155 people aboard were rescued by nearby boats and there were few serious injuries. Chesley Burnett "Sully" Sullenberger III (born 1951) is an American retired airline captain celebrated for the January 15, 2009 water landing of US Airways Flight 1549 in the Hudson River off Manhattan after the plane was disabled by striking a flock of Canada geese immediately after takeoff; all 155 people aboard survived.  Sullenberger is an international speaker on airline safety and has helped develop new protocols for airline safety.  He served as the co-chairman, along with First Officer Jeffrey Skiles, of the EAA's Young Eagles youth introduction-to-aviation program from 2009 to 2013.  He retired from US Airways after 30 years as a commercial pilot on March 3, 2010.  In May of the following year, Sullenberger was hired by CBS News as an Aviation and Safety Expert. Highest Duty: My Search for What Really Matters is a memoir written by Chesley Sullenberger and Jeffrey Zaslow (1958–2012) describing the events of US Airways Flight 1549.  The "New York Times" bestselling autobiography of Capt. Chesley “Sully” Sullenberger—the pilot who landed a crippled airplane in New York's Hudson River, saving the lives of the 155 passengers—discusses leadership, responsibility, and service, along with his life story. Fly by Wire: The Geese, the Glide, the Miracle on the Hudson is a book written in 2009 by William Langewiesche about US Airways Flight 1549 with emphasis on the role played by the advanced fly-by-wire flight control system of the aircraft.
