input: Sullenberger was employed by US Airways and its predecessor airlines from 1980 until 2010. (Pacific Southwest Airlines was acquired by US Air, later US Airways, in 1988.) He holds an Airline Transport Pilot Certificate for single and multi-engine airplanes, and a Commercial Pilot Certificate rating in gliders, as well as a flight instructor certificate for airplanes (single, multi-engine, and instrument), and gliders. In total, he has more than 40 years and 20,000 hours of flying experience. In 2007, he became the founder and CEO of Safety Reliability Methods, Inc. (SRM), a firm providing strategic and tactical guidance to enhance organizational safety, performance, and reliability.  He has also been involved in a number of accident investigations conducted by the USAF and the National Transportation Safety Board (NTSB), such as Pacific Southwest Airlines Flight 1771 and USAir Flight 1493. He served as an instructor, Air Line Pilots Association Local Air Safety Chairman, accident investigator, and national technical committee member. His safety work for ALPA led to the development of a Federal Aviation Administration Advisory Circular. He was instrumental in developing and implementing the Crew Resource Management course that is used by US Airways, and he has taught the course to hundreds of airline crew members.  Working with NASA scientists, he coauthored a paper on error-inducing contexts in aviation. He was an air accident investigator for an NTSB inquiry into a major accident at Los Angeles International Airport, which "led to improved airline procedures and training for emergency evacuations of aircraft". Sullenberger has also been studying the psychology behind keeping an airline crew functioning during a crisis.  Sullenberger was active with his union, serving as chairman of a safety committee within the Air Line Pilots Association.  He was a featured speaker for two panels, one on aviation and one on patient safety in medicine, at the High Reliability Organizations (HRO) 2007 International Conference in Deauville, France, from May 29 to 31, 2007.

input: Garibaldi deeply disliked the Sardinian Prime Minister, Camillo Benso, Count of Cavour. To an extent, he simply mistrusted Cavour's pragmatism and realpolitik, but he also bore a personal grudge for Cavour's trading away his home city of Nice to the French the previous year. On the other hand, he felt attracted toward the Piedmontese monarch, who in his opinion had been chosen by Providence for the liberation of Italy. In his famous meeting with Victor Emmanuel II at Teano on 26 October 1860, Garibaldi greeted him as King of Italy and shook his hand. Garibaldi rode into Naples at the king's side on 7 November, then retired to the rocky island of Caprera, refusing to accept any reward for his services.  At the outbreak of the American Civil War (in 1861), Garibaldi volunteered his services to President Abraham Lincoln. Garibaldi was offered a major general's commission in the U. S. Army through the letter from Secretary of State William H. Seward to H. S. Sanford, the U. S. Minister at Brussels, July 17, 1861. On September 18, 1861, Sanford sent the following reply to Seward:  He [Garibaldi] said that the only way in which he could render service, as he ardently desired to do, to the cause of the United States, was as Commander-in-chief of its forces, that he would only go as such, and with the additional contingent power--to be governed by events--of declaring the abolition of slavery; that he would be of little use without the first, and without the second it would appear like a civil war in which the world at large could have little interest or sympathy.  These conditions could not be met. On August 6, 1863, after the Emancipation Proclamation had been issued, Garibaldi wrote to Lincoln, "Posterity will call you the great emancipator, a more enviable title than any crown could be, and greater than any merely mundane treasure".  On 5 October 1861 Garibaldi set up the International Legion bringing together different national divisions of French, Poles, Swiss, German and other nationalities, with a view not just of finishing the liberation of Italy, but also of their homelands. With the motto "Free from the Alps to the Adriatic," the unification movement set its gaze on Rome and Venice. Mazzini was discontented with the perpetuation of monarchial government, and continued to agitate for a republic. Garibaldi, frustrated at inaction by the king, and bristling over perceived snubs, organized a new venture. This time, he intended to take on the Papal States.
