Input: Consider Input: "2017 was a strong year for Facebook  but it was also a hard one " Facebook founder and  CEO Mark Zuckerberg  said in a statement. "In 2018  we're focused on making sure Facebook isn't just fun to use  but also good for people's well-being and for society. We're doing this by encouraging meaningful connections between people rather than passive consumption of content."
 Zuckerberg  noted that the company's recent news feed changes  such as reducing the volume of viral videos  have caused time spent on Facebook to decline by about 50 million hours every day - an average of about 2 minutes per person every day.
On a conference call with investors   Zuckerberg  emphasized that time spent alone offers limited insight into the value of the social network and that  he  expects short-term drops in time on the site to make the product stronger in the long-term.
"By focusing on meaningful interactions  I believe that the time spent on Facebook will be more valuable "  Zuckerberg  said. "If people interact more  it should lead to stronger community. When you care about something  you’re willing to see ads to experience it."
Facebook’s results come just a few weeks after  Zuckerberg  announced that  the company  plans to make a year-long shift across  its  products to prioritize interactions between friends and family and reduce the prominence of unpaid posts by brands and publishers. In the near-term  the change will cause news to make up only 4% of news feed  down from about 5% currently. Facebook plans to display news sources in accordance with how users rank their “trustworthiness.”  Zuckerberg  also said  the company  plans to elevate local news in a push to help “build community.” Facebook correctly warned that the changes could lead to a decrease in time spent on the social network in the short-term. However   Zuckerberg  has said  he  sees the shift as critical to Facebook’s long-term success as a business and product.
When Facebook reported its third quarterly earnings in November   Zuckerberg  said  he  was “dead serious” about addressing the social network’s security and safety issues  ranging from election meddling to moderation issues  such as violent live videos and misinformation.  Zuckerberg  warned that the bolstered efforts “will impact” the company’s profitability.  The company  said last year  it  plans to double  its  headcount working on safety and security from 10 000 people to 20 000 people over the course of 2018  and add thousands more content moderators. (Facebook said it has 25 105 employees as of December 31  up 47% from a year earlier.)
Zuckerberg continues to emphasize video advertising as key to the future of the company’s business. Facebook recently added a “Watch” section for video shows and series  which competes with Google-owned YouTube and is intended in the long-term to foster interaction between friends  family and groups. Higher-quality content in the tab could drive stronger video ad sales over time.  Zuckerberg  also noted in Wednesday's conference call that  he  expects "Stories" -- chains of disappearing photos and videos -- to overtake posts and feeds as the most common content format across apps  and that the growth of the feature will shape how Facebook evolves its apps and business.

Input: Consider Input: Astronaut John Young (Photo: NASA)
Astronaut John Young  who walked on the moon and was the first to fly into space six times  died Friday night at 87.
In a statement  acting NASA Administrator Robert Lightfoot said  Young  died from complications from pneumonia. He called  Young  NASA's "most experienced astronaut."
“Today  NASA and the world have lost a pioneer " Lightfoot said. " Astronaut John Young 's storied career spanned three generations of spaceflight; we will stand on his shoulders as we look toward the next human frontier."
A former fighter pilot   Young  started  his  career with NASA in 1962.  His  first flight as an astronaut came in March 1965 aboard the Gemini 3 with fellow astronaut Gus Grissom.  He  went to the moon in May 1969 aboard Apollo 10 and again in April 1972 on Apollo 16.
 Young  had gone into space as apart of the Gemini  Apollo and space shuttle programs  the only NASA astronaut to be a part of all three  Lightfoot said.

Input: Consider Input: The plane was manned by Marine Capt. Richard Ashby  a 30-year-old on his final training flight before promotion to fighter pilot  and Capt.  Joseph Schweitzer   a navigator with a decade of flight experience. Capt. William Raney and Capt. Chandler Seagraves  electronic-warfare officers  were in the back seats.
During the flight   Schweitzer  borrowed Ashbyâs handheld videocamera to record  his  swan songâ his  last aerial navigation as a Marine Corps pilot before  he  left the military.  Schweitzer  testified that  he  had intended to show the video to  his  kids someday.
The plane lost contact with ground radar at 3:06 p.m. due to its low altitude  and  Schweitzer  testified that the video showed  him  smiling right up until 3:12 p.m.  when the plane hit the gondola cable.
After hitting the cable  the pilots saw the gondola fall but continued their flight. They landed the damaged Prowler safely at a NATO base in Aviano  in northern Italy. Court documents show that as Raney and Seagraves got off the plane   Schweitzer  and Ashby remained behind  took the borrowed camcorder videotape of the flight  then replaced it with a blank tape.
As  Schweitzer  and Ashby walked to the mess hall a few days after the accident  they asked Seagravesâ advice on handling questions about the videotape  according to court documents. Seagraves testified that he counseled the pilots to âget rid of the videotape. If  it  were mine  I would get rid of  it .â
Court documents show that Ashby gave  Schweitzer  the videotape  and  Schweitzer  took  it  outside behind a bar and threw  it  into a bonfire  despite âknowing that Italian and United States military criminal investigators would have wanted to view  it  â according to  his  testimony (PDF).
â Get rid of the videotape. If  it  were mine  I would get rid of  it . â â Capt. Chandler Seagraves in court testimony
Initially  all four men were charged with crimes and Ashby  who had been at the controls  faced a total of more than 200 years in a military prison.  Schweitzer  and Ashby were recommended for general court-martial at Camp Lejeune on 20 counts of involuntary manslaughter and negligent homicide. Italian authorities did not have jurisdiction to formally charge the crew members under NATO treaty rules.
The planeâs pilot and navigator  Ashby and Schweitzer  were court-martialed again in May 1999 on charges of obstructing justice by destroying the videotape recorded during the flight. Guilty verdicts pushed Ashby and  Schweitzer  out of the Marine Corps  and Ashby served four months of a six-month term in military prison before his release on good behavior.
Ashby and  Schweitzer  maintained that they had seen neither the new directives nor the updated government maps. Seagraves and Raney testified that the altitude gauge did not trigger after the plane entered the Cermis valley  even though Ashby  the pilot  had set the indicator to go off when they dropped below 800 feet  according to the Associated Press.
The investigationâs partially redacted pages blamed the Marine pilots for the tragedy and advised the United States to take full responsibility for paying restitution to the victimsâ families  La Stampa reported. The paper added that investigators found compelling evidence refuting the crew membersâ claims regarding old maps and missed flight directives that eventually led to  Schweitzer  and Ashbyâs acquittal on the most severe charges.
The Daily Beast interviewed retired Maj. Raney and then-Capt.  Schweitzer about the La Stampa  claims. Both crew members denied having seen or read the new directives or maps marking the location of the cable-car lines.
âNo   we  absolutely did not have charts with the cables marked on them â Raney said. âThe Italians had the cables marked on their maps  but  we  did notâ¦ and there was a two-star [general] who flat out lied about it in a press conference.
âYou know  this is a situation that I like to call the unbelievable  unimaginable  unexpected moments that training just canât prepare you for â  Schweitzer  said. âI got rid of the tape  not because of the flight  but because that was my worst nightmareâ¦ I didnât want to look at my smiling face while flying a low-altitude flight  which was something I loved to doâand then all of a sudden  tragedy.â
In a 2015 email to The Daily Beast via a public-affairs spokesperson   he  wrote that the Cavalese cable-car incident has been fully investigated  but  he  also offered  his  condolences.
âI would like to extend my heartfelt sympathies to everyone affected by this tragedy â  he  wrote.
