Australian military gets first drone that can fly with artificial intelligence

  Australian military gets first drone that can fly with artificial intelligence Boeing has presented the Australian Air Force with a prototype of a jet-powered drone that they hope will one day fly alongside manned warplanes.Australia has its first "loyal wingman.

  • This week, the grounded Boeing 737 MAX is being tested for flight recertification in Washington.
  • The plane's overly engineered software failed in two high-profile, high-casualty crashes.
  • Federal Aviation Administration (FAA) approval will take months, with international scrutiny to follow.

The troubled Boeing 737 MAX is singing for its supper for what may be the last time this week, undergoing test flights with changes Boeing says will bring the infamous airplane back into safe operating parameters. Flight tests began on Monday. Can this airplane be saved?

Boeing-built X-37B space plane goes into orbit for shadowy Space Force test mission

  Boeing-built X-37B space plane goes into orbit for shadowy Space Force test mission An Atlas 5 rocket launched a Boeing-built X-37B space plane on a semi-secret orbital mission under the management of the recently created Space Force. Today’s USSF-7 launch from Cape Canaveral Air Force Station in Florida came at 9:14 a.m. ET (6:14 a.m. PT), a day after the first attempt was called off due to weather. This is the sixth test flight of an X-37B, the first such flight to have a service module attached to the space plane’s aft, and the first carried out under the Space Force’s banner. ULA dedicated the launch to those affected by COVID-19 as well as first responders and front-line workers. The U.S.

The 737 MAX was grounded after its complication software failed in similar ways on two flights in 2018 and 2019 that crashed and killed a combined nearly 350 people. During the design and building of the MAX, Boeing cut corners with “hardware” in terms of power and engineering and said it made up for it with the advanced software and electronic monitoring systems. The proprietary anti-stall software contributed to both crashes, but was far from the only problem inside the MAX.

After the plane was grounded in March 2019, Boeing has pushed out a series of software fixes it claims will help make the MAX stable and safe for flight. But the software fixes grew larger and larger until they choked the MAX’s reliable, albeit low-powered flight computers. When the new software showed signs of the same problems as before, global aviation authorities started to say they’d insist on approving the MAX on an individual basis instead of taking the U.S. authorities’ word for it.

Boeing resumes production of its troubled 737 Max airplane

  Boeing resumes production of its troubled 737 Max airplane The plane has yet to be cleared by the FAA to return to passenger service . Investigators have discovered numerous software glitches, apart from the MCAS flight control system that has been identified as the cause of the fatal crashes. Boeing said that during the temporary suspension, the company’s mechanics and engineers worked together to “standardize work packages” and revamp the “kitting process” to ensure that employees have everything they need to build the airplane.

Before the COVID-19 (coronavirus) pandemic that reduced flights around the world and parked thousands of airliners for the duration, Boeing was still struggling; the grounded MAX could not be sold, despite enormous demand. If Boeing can get the plane in the air again now, it might pull its finances out of a tailspin. In the meantime, Boeing has laid off 10 percent of its workforce, which constitutes 16,000 workers.

A test like this, to recertify a grounded airplane, must be designed to address whatever the specific problem was. In this case, with faulty software in question, any new approval will rely on data collected during test flights with the new software. The New York Times reports on the Federal Aviation Administration’s (FAA) description of the tests: “a wide array of flight maneuvers and emergency procedures to enable the agency to assess whether the changes meet FAA certification standards."

Which TV Shows Are Renewed and Which Are Canceled? Your 2020-2021 Guide

  Which TV Shows Are Renewed and Which Are Canceled? Your 2020-2021 Guide It’s that time of year again, so hit your bookmark button now. Us Weekly will continue to track every show renewal and cancelation below. This time, there are a few shows that have changed their course. For example, Fox’s The Orville will not return to network TV for its third season; instead, it will head to Hulu. Since the third season would not be ready for midseason debut, creator Seth MacFarlane decided to go elsewhere — and the first two seasons are already available to watch there. “As the show has evolved and become more ambitious production-wise, I determined that I would not be able to deliver episodes until 2020, which would be challenging for the network. So we began to discuss how best to support the third season in a way that worked for the show,” he said in a statement in July 2019. “It’s exactly this kind of willingness to accommodate a show’s creative needs that’s made me want to stick around for so long.” While some shows are making moves to streaming platforms, others are currently in their final season. Supernatural, The CW’s biggest hit show, is set to wrap up in spring 2020 after 15 seasons. “We’re going to get to see characters again that we haven’t seen in a long time, but then most of those characters are also going to die. We’re going to be resurrecting a lot of old favorites only to kill them again,” star Misha Collins told Us exclusively in November. “It is going to feel like it has a high degree of finality to it.

In software testing, programmers use carefully written sets of inputs or actions to make sure they’re testing all possible or feasible paths users will take in the software. In this case, the FAA is conducting a test that includes all the ways the 737 MAX’s programming could fail. That includes triggering the previously faulty Maneuvering Characteristics Augmentation System (MCAS) that failed in both high-casualty crashes.

“The rigors of the test campaign go beyond previous Boeing test flights, completed in a matter of hours on a single day, industry sources say,” the Times reports. Boeing has reportedly been able to do a complete dry run with the exact specifications as the planned FAA tests. Even if this test goes perfectly over several days, the results won’t be conclusive until September, FAA officials told the Times.

In the most optimistic, successful timeline, that means the Boeing 737 MAX could be back in the air by the very end of 2020 at the earliest.
