Federal regulators head to Capitol Hill Wednesday following weeks of revelations about problems with the fatally flawed Boeing 737 Max, and as the world awaits a software fix and revised training program from the aircraft's manufacturer.The Federal Aviation Administration's current acting administrator, Daniel Elwell, is expected to face questions from lawmakers about how the Max was certified, and what steps will be taken to assure a skittish flying public that the aircraft can safely return to the skies.The Trump administration's nominee for the job, Stephen Dickson, will testify at a separate hearing. Dickson is a former Delta Air Lines executive and military pilot, and has not yet publicly commented on the 737 MAX or its grounding, which occurred days before his nomination was announced. In a Senate questionnaire prior to the hearing, Dickson identified safety as one of his qualifications for and priorities on the job.The FAA is waiting on Boeing to complete a software update for its review. The 737 Max 8 and 9 were grounded worldwide after a second crash in Ethiopia two months ago that investigators have described as appearing similar to an October crash into the Java Sea. Between the Lion Air and Ethiopian Airlines crashes, 346 people were killed.When Elwell testified in late March, about two weeks after the Ethiopian crash, he defended the agency's process for grounding the plane. Other countries that acted days earlier, he said, without the data that the FAA waited for.Since then, news reports have revealed how the FAA certification process allowed Boeing officials with authority delegated from the FAA to certify their company's own work.Elwell will be joined by the agency's executive director of aircraft certification, Earl Lawrence, and two officials from the National Transportation Safety Board, which represents the United States in the Indonesian and Ethiopian investigations.Preliminary reports on both crashes have implicated a flight control system that Boeing designed to operate in the background, making the 737 Max fly like earlier versions of the workhorse jetliner. Maintaining enough similarities between the planes avoided costly pilot training programs, a fact Boeing touted as a selling point.But that computerized stability program -- the Maneuvering Characteristics Augmentation System, or MCAS -- received faulty sensor readings in both the Lion Air and Ethiopian jets, and repeatedly pushed the planes' noses downward, and ultimately into steep dives. The pilots' attempts to overcome it were unsuccessful. As is standard practice, the preliminary reports did not lay blame for either accident.The emergency flight procedure Boeing says pilots should rely on when the system malfunctions has not been substantially updated since the 1960s and is now under FAA review, CNN recently reported.But Boeing admitted its software could be improved to break what it described as links in the chains of events that ended in the crashes.Boeing did not perform a flight test of a scenario where the system malfunctioned, CNN has reported. 3100

Hardline Brexiteer Boris Johnson has won the UK's Conservative Party leadership contest and will take over from outgoing Prime Minister Theresa May when she steps down on Wednesday.Johnson, a former Mayor of London and British Foreign Secretary, was officially named the new Tory leader on Tuesday, beating his rival Jeremy Hunt in a ballot of party members.The leadership vote was triggered after an embattled May was forced into resigning after losing the support of her cabinet, many of whom were fed up with her inability to secure the UK's departure from the European Union (EU).As prime minister, Johnson, 55, will inherit the same problems of a deeply divided Parliament -- and nation -- when he assumes the role.Throughout his leadership campaign, Johnson was vocal about his willingness to exit the EU without a deal, pledging to leave "do or die" on October 31, the latest deadline for the UK to depart the bloc.He said that he'd be willing to force Brexit through on that date by suspending Parliament, if he's unable to negotiate a new exit deal with EU officials.The EU has said there is no chance of reopening the Withdrawal Agreement, the deal that May made with the bloc in 2018 but which has failed to satisfy both the Europhile and Euroskeptic wings of both the Tory party and Parliament.While Johnson's stance on Brexit have defined his leadership bid, his incendiary remarks on religion and race have sparked criticism about his character.Writing in his weekly column in the British newspaper the Daily Telegraph last August, he likened Muslim women wearing veils to "letter boxes" and "bank robbers."Earlier this month, he faced new accusations of Islamophobia after claiming in a newly-unearthed 2007 text that Islam left Muslim countries "centuries behind" the Western world.Previously, Johnson called people from the British Commonwealth "flag-waving piccaninnies," referred to the " 1919
