Steele dossier <=SEP=> The Steele dossier, also known as the Trump–Russia dossier, is a political opposition research report written from June to December 2016 containing allegations of misconduct, conspiracy, and co-operation between Donald Trump's presidential campaign and the government of Russia during the 2016 election. The Guardian has described the controversial opposition research as "one of the most explosive documents in modern political history". The dossier, leaked without permission, is an unfinished 35-page compilation of raw intelligence based on information from witting and unwitting anonymous sources known to the author, counterintelligence specialist Christopher Steele, a former head of the Russia Desk for British intelligence (MI6), written for the private investigative firm Fusion GPS. The dossier's 17 unredacted reports allege that Trump campaign members and Russian operatives had conspired to co-operate in Russia's election interference to benefit Trump. It also alleges that Russia sought to damage Hillary Clinton's candidacy, including sharing negative information about Clinton with the Trump campaign. The draft dossier was published in full by BuzzFeed News on January 10, 2017, noting that it was unverified. This was done without permission from Orbis Business Intelligence or Steele. Several mainstream media outlets criticized BuzzFeed's decision to publish the reports without verifying their allegations, while others defended its decision.

D. B. Cooper <=SEP=> D. B. Cooper is a media epithet popularly used to refer to an unidentified man who hijacked a Boeing 727 aircraft in the airspace between Portland , Oregon , and Seattle , Washington , on November 24 , 1971 . He extorted $ 200,000 in ransom and parachuted to an uncertain fate . Despite an extensive manhunt and protracted FBI investigation , the perpetrator has never been located or identified . The case remains the only unsolved air piracy in commercial aviation history .   While available evidence and a preponderance of expert opinion suggested from the beginning that Cooper probably did not survive his high-risk jump , the FBI nevertheless maintained an active investigation for 45 years following the hijacking . Despite a case file that grew to over 60 volumes over that time period , no definitive conclusions have been reached regarding Cooper 's true identity or whereabouts . The suspect purchased his airline ticket using the alias Dan Cooper , but because of a news media miscommunication he became known in popular lore as `` D. B. Cooper '' .   Numerous theories of widely varying plausibility have been proposed over the years by investigators , reporters , and amateur enthusiasts . The discovery of a small cache of ransom bills along the banks of the Columbia River in February 1980 triggered renewed interest , but ultimately only deepened the mystery , and the great majority of the ransom remains unrecovered .   The FBI officially suspended active investigation of the case in July 2016 , but continues to request that any physical evidence that might emerge related to the parachutes or the ransom money be submitted for analysis .

Roswell UFO incident <=SEP=> In mid-1947 , a United States Air Force balloon crashed at a ranch near Roswell , New Mexico . Following wide initial interest in the crashed `` flying disc '' , the US military stated that it was merely a conventional weather balloon . Interest subsequently waned until the late 1970s , when ufologists began promoting a variety of increasingly elaborate conspiracy theories , claiming that one or more alien spacecraft had crash-landed , and that the extraterrestrial occupants had been recovered by the military , who then engaged in a cover-up .   In the 1990s , the US military published two reports disclosing the true nature of the crashed object : a nuclear test surveillance balloon from Project Mogul . Nevertheless , the Roswell incident continues to be of interest in popular media , and conspiracy theories surrounding the event persist . Roswell has been described as `` the world 's most famous , most exhaustively investigated , and most thoroughly debunked UFO claim '' .

Criticism of NASCAR <=SEP=> The National Association for Stock Car Auto Racing ( NASCAR ) is the sanctioning body for the Monster Energy NASCAR Cup Series , the Xfinity Series and the Camping World Truck Series . NASCAR also oversees a number of regional racing series , including the Whelen Modified Tour , and the Whelen All-American Series . In its role , NASCAR sanctions over 1,500 races at over 100 tracks in 39 states , Canada , Mexico , and Europe .   Similar to other professional leagues and sanctioning bodies , NASCAR has been the target of criticism on various topics , from various sources . Some critics note the significant differences between today 's NASCAR vehicles and true `` stock cars '' . As NASCAR has made moves to improve its national appeal , it has begun racing at new tracks , and ceased racing at some traditional ones , a sore spot for the traditional fan base .   Others frequently cite the dominance of the France family in NASCAR 's business structure , policies , and decision making . Recently , the increased number of Cup drivers competing consistently in the Xfinity Series races has been hotly debated . Most recently , NASCAR has been challenged on the types and frequency of caution flags , with some critics suggesting the outcome of races is being manipulated , and that the intention is not safety , as NASCAR claims , but closer racing .   Another general area of criticism , not only of NASCAR but other motorsports as well , includes questions about fuel consumption , emissions and pollution , and the use of lead additives in the gasoline .
