Question: Who attacked American Airlines Flight 444, in a nationwide bombing campaign that targeted people involved with modern technology?
Context: From February 20–25, 1944, as part of the European strategic bombing campaign, the United States Strategic Air Forces (USSTAF) launched Operation Argument, a series of missions against Nazi Germany that became known as Big Week.  The planners intended to lure the Luftwaffe into a decisive battle by launching massive attacks on the German aircraft industry.  By defeating the Luftwaffe, the Allies would achieve air superiority and the invasion of continental Europe could proceed.  The daylight bombing campaign was also supported by RAF Bomber Command, operating against the same targets at night.  Arthur Harris resisted contributing RAF forces as it diverted them from the British area bombing offensive.  It took a direct order from Air Chief Marshal Sir Charles Portal, Chief of the Air Staff, to force Harris to comply.  RAF Fighter Command also provided escort for USAAF bomber formations, just at the time that the Eighth Air Force had started introducing the P-51 long-range fighter to take over the role.  This major offensive overlapped the German Operation Steinbock, the "baby blitz" against the United Kingdom, which itself lasted from January through May 1944. This is a list of aviation-related events from 1985.  It remains one of the deadliest years in aviation history for aviation disasters, including the crash of Japan Airlines Flight 123, bombing of Air India Flight 182, crash of Arrow Air Flight 1285, crash of Aeroflot Flight 7425, crash of Iberia Airlines Flight 610, Delta Air Lines Flight 191, Galaxy Airlines Flight 203, and British Airtours Flight 28M, a mid-air collision between Aeroflot Flight 8381 and a Soviet Air Forces transport aircraft, the hijacking of Egyptair Flight 648, and various crashes and other incidents with under 50 fatalities.  August 1985 remains the worst single month for commercial aviation fatalities in history. American Airlines Flight 444 was a Boeing 727 flying from Chicago to Washington, D.C.'s National Airport, which on November 15, 1979, was attacked by the Unabomber.  The bomb planted in the cargo hold caused "a sucking explosion and a loss of pressure," which was then followed by large quantities of smoke filling the passenger cabin, forcing the pilots to make an emergency landing at Dulles International Airport.  Twelve passengers had to be treated afterward for smoke inhalation.  It was later determined that the bomb was powerful enough to have destroyed the aircraft had it worked correctly. American Airlines Flight 587 was a regularly scheduled passenger flight from John F. Kennedy International Airport in New York City to Las Américas International Airport in Santo Domingo in the Dominican Republic.  On November 12, 2001, the Airbus A300-600 flying the route crashed shortly after takeoff into the Belle Harbor neighborhood of Queens, a borough of New York City.  All 260 people aboard the plane (251 passengers and nine crew members) died, including one dog carried in the cargo hold; five bystanders and one other dog on the ground were killed as well.  It is the second-deadliest aviation incident in New York State, the second-deadliest aviation incident involving an Airbus A300 (after Iran Air Flight 655), and the second-deadliest aviation accident to occur on U.S. soil (after American Airlines Flight 191).  No commercial airplane crash since then that was ruled accidental and not criminal has even surpassed that death toll, even though there had been deadlier incidents of this type before 2001. The Hamburg cell (German: "Hamburger Zelle" ) or Hamburg terror cell (German: "Hamburger Terrorzelle" ) was, according to U.S. and German intelligence agencies, a group of radical Islamists based in Hamburg, Germany that included students who eventually came to be key operatives in the 9/11 attacks.  Important members included Mohamed Atta, who led the four hijacking teams in 2001 and piloted American Airlines Flight 11; Ramzi bin al-Shibh, who conspired with the other three members but was unable to enter the United States; and Marwan al-Shehhi, who piloted United Airlines Flight 175, Ziad Jarrah, who piloted United Airlines Flight 93 and failed to hit a target in Washington D.C., claimed by Khalid Sheikh Mohammed to have been the Capitol.  Less important members included Said Bahaji, Zakariya Essabar, Mounir el-Motassadeq, and Abdelghani Mzoudi. Capital Airlines Flight 67 was domestic scheduled passenger flight operated by Capital Airlines that crashed on final approach to Freeland, Michigan, USA, during a severe snowstorm on April 6, 1958.  The flight was en route from Flint-Bishop Airport to the Freeland-Tri City Airport (now MBS International Airport) when it crashed.  Flight 67 was the first of four fatal crashes in the space of two years involving Capital Airlines Vickers Viscounts; the others were Capital Airlines Flight 300 (May 1958), Capital Airlines Flight 75 (May 1959) and Capital Airlines Flight 20 (January 1960). Operation Menu was the codename of a covert United States Strategic Air Command (SAC) bombing campaign conducted in eastern Cambodia from 18 March 1969 until 26 May 1970, during the Vietnam War.  The targets of these attacks were sanctuaries and Base Areas of the People's Army of Vietnam (PAVN) and forces of the Viet Cong, which utilized them for resupply, training, and resting between campaigns across the border in the Republic of Vietnam (South Vietnam).  The impact of the bombing campaign on the Khmer Rouge guerrillas, the PAVN, and Cambodian civilians in the bombed areas is disputed by historians. Theodore John Kaczynski ( ; born May 22, 1942), also known as the Unabomber, is an American mathematician, anarchist and domestic terrorist.  A mathematical prodigy, he abandoned a promising academic career in 1969, then between 1978 and 1995 killed 3 people, and injured 23 others, in a nationwide bombing campaign that targeted people involved with modern technology.  In conjunction, he issued a wide-ranging social critique opposing industrialization and advancing a nature-centered form of anarchism. Northwest Airlines Flight 253 was an international passenger flight from Amsterdam Airport Schiphol in Haarlemmermeer, Netherlands, to Detroit Metropolitan Wayne County Airport in Romulus, Michigan, United States.  The flight was the target of a failed al-Qaeda bombing attempt on Christmas Day, December 25, 2009, in which a passenger tried to set off plastic explosives sewn to his underwear.  There were 290 people on board the aircraft—an Airbus A330-323E operated by Northwest Airlines, which had merged with Delta Air Lines the year before.  Had the attempt succeeded, it would have surpassed American Airlines Flight 191 as the deadliest aviation occurrence on U.S. soil and tied Iran Air Flight 655 as the eighth-deadliest of all time.  The incident was also the second in 2009 involving an Airbus A330, after the crash of Air France Flight 447 on June 1.  This was also the final accident/incident involving Northwest Airlines as it closed down a month later when it merged with Delta Air Lines. American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda members on September 11, 2001, as part of the September 11 attacks.  Mohamed Atta deliberately crashed the plane into the North Tower of the World Trade Center in New York City, killing all 92 people aboard and an unknown number in the building's impact zone.  The aircraft involved, a Boeing 767-223ER, registration N334AA, was flying American Airlines' daily scheduled morning transcontinental service from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California.
