Background: Knievel was born on October 17, 1938, in Butte, Montana, the first of two children of Robert E. and Ann Marie Keough Knievel. His surname is of German origin; his paternal great-great-grandparents emigrated to the United States from Germany. His mother was of Irish ancestry. Robert and Ann divorced in 1940, after the 1939 birth of their second child, Nicolas, known as Nic.
Context: ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie theaters. Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.  The launch took place at the south rim of the Snake River Canyon, west of Shoshone Falls (42.597degN 114.423degW / 42.597; -114.423), on Sunday, September 8, 1974, at 3:36 p.m. MDT. The steam that powered the engine was superheated to a temperature of 500 degF (260 degC). The drogue parachute prematurely deployed as the Skycycle left the launching rail and induced significant drag. Even though the craft made it all the way across the canyon to the north rim, the prevailing northwest winds caused it to drift back into the canyon. By the time it hit the bottom of the canyon, it landed only a few feet from the water on the same side of the canyon from which it had been launched. If he had landed in the water, Knievel likely would have drowned, due to a jumpsuit/harness malfunction which kept him strapped in the vehicle. He survived the jump with only minor injuries.  Since the 1974 launch, seven daredevils have expressed interest in recreating the jump, including Knievel's two sons, Robbie and Kelly. In 2010 Robbie announced he would recreate the jump. Stuntman Eddie Braun announced he was working with Kelly and Robert Truax's son to recreate the jump using a replica of the Skycycle X-2. Braun's jump took place on September 16, 2016, and was completed successfully.
Question: was the launch successful?
Answer: Even though the craft made it all the way across the canyon to the north rim, the prevailing northwest winds caused it to drift back into the canyon.

Problem: Background: William McKinley (January 29, 1843 - September 14, 1901) was the 25th President of the United States, serving from March 4, 1897 until his assassination in September 1901, six months into his second term. McKinley led the nation to victory in the Spanish-American War, raised protective tariffs to promote American industry, and maintained the nation on the gold standard in a rejection of free silver (effectively, expansionary monetary policy). McKinley was the last president to have served in the American Civil War, and the only one to have started the war as an enlisted soldier, beginning as a private in the Union Army and ending as a brevet major.
Context: William McKinley Jr. was born in 1843 in Niles, Ohio, the seventh child of William McKinley Sr. and Nancy (nee Allison) McKinley (1809-1897). The McKinleys were of English and Scots-Irish descent and had settled in western Pennsylvania in the 18th century, tracing back to a David McKinley who was born in Dervock, County Antrim, in present-day Northern Ireland. There, the elder McKinley was born in Pine Township, Mercer County.  The family moved to Ohio when the senior McKinley was a boy, settling in New Lisbon (now Lisbon). He met Nancy Allison there, and married her later. The Allison family was of mostly English descent and among Pennsylvania's earliest settlers. The family trade on both sides was iron-making, and McKinley senior operated foundries throughout Ohio, in New Lisbon, Niles, Poland, and finally Canton. The McKinley household was, like many from Ohio's Western Reserve, steeped in Whiggish and abolitionist sentiment, the latter based on the family's staunch Methodist beliefs. William followed in the Methodist tradition, becoming active in the local Methodist church at the age of sixteen. He was a lifelong pious Methodist.  In 1852, the family moved from Niles to Poland, Ohio so that their children could attend the better schools there. Graduating from Poland Seminary in 1859, he enrolled the following year at Allegheny College in Meadville, Pennsylvania. He remained at Allegheny for only one year, returning home in 1860 after becoming ill and depressed. He also spent time at Mount Union College in Alliance, Ohio as a board member. Although his health recovered, family finances declined and McKinley was unable to return to Allegheny, first working as a postal clerk and later taking a job teaching at a school near Poland, Ohio.
Question: did he have any siblings?
Answer:
the seventh child of William McKinley Sr. and Nancy (nee Allison) McKinley
