The report also plays down the potential aerial dangers that could be posed by UAPs by noting that the AARO had received no reports during the collection period that suggested that "UAP maneuvered to an unsafe proximity to civil or military aircraft, positioned themselves in flight paths, or otherwise posed a direct threat to flight safety of the observing aircraft."In an ABC News interview this past summer, Dr. Sean Kirkpatrick, the head of AARO, said that being caught off guard by "intelligent or extraterrestrial technical surprise" remained a top concern."Data and science has to guide where you go, and we will follow the data," Kirkpatrick said then.In late August, the Pentagon launched a new website to serve as a one-stop clearinghouse for unclassified information about UAPs.The platform includes unclassified videos and photos of resolved cases as well as links to reports and other resources. It will soon have a feature enabling AARO to accept reports "from current or former U.S. Government employees, service members, or contractors with direct knowledge of U.S. Government programs or activities related to UAP dating back to 1945."In June, the Pentagon issued a statement that "to date, AARO has not discovered any verifiable information to substantiate claims that any programs regarding the possession or reverse-engineering of extraterrestrial materials have existed in the past or exist currently."The was issued in response to unconfirmed claims by David Grusch, a former intelligence official who said he was stepping forward as a whistleblower to say that the U.S. had been collecting non-human craft for "decades."In late July, a House Government Oversight subcommittee held a hearing where Grusch went public with his allegations and urged Congress to investigate.。关联期权合约如下图所示：标的品种：苯乙烯（主力最新价8512.0，跌幅5.07%）合约名称剩余日最新价涨跌幅（昨收）苯乙烯2610沽830021140124%苯乙烯2610沽840021175.5120.75%苯乙烯2610沽80002165.5118.33%苯乙烯2610沽850021224115.38%苯乙烯2610沽860021277.5110.23%期权实战案例持有500吨苯乙烯，怎样用看跌期权给货值上保险？苯乙烯现货商小李持有500吨货源，对应货值按8300元/吨估算约415万元，担心价格下跌。8月26日...。
