"nightly news" begins now.

>> announcer: from nbc news world headquarters in new york this is "nbc nightly news" with brian williams. >> good evening. i'm lester holt sitting in tonight for brian. there's such deep anguish for families of those aboard airasia 8501. debris and the bodies retrieved from the java sea today left little doubt about the fate of the plane and the 162 people on board. a blue suitcase an oxygen tank what appears to be an undeployed emergency slide are some of the items officials have now confirmed came from the jet. the debris from the airbus was discovered off the west coast of borneo roughly in line with the plane's flight path. with help of the united states standing by to help find and recover the jet's flight recorders, early indications suggest the flight met a sudden end as the crew tried to negotiate around violent thunderstorm cells in their path. once again tonight we're covering several angles of this story.

let's start with katy tur in singapore with the latest on the search. katy? >> reporter: lester it is now day four of this search and rescue. they're going to be looking for more wreckage more debris more bodies especially even survivors. it was a tough day yesterday, it's going to be a tough day again today, but a lot of relatives say they're not going to give up hope that somebody might be found alive. at surabaya airport all consuming grief. indonesian officials confirming they found the wreckage of airasia flight 8501. life vests and luggage floating alongside bodies as well as a shadow that could be a large part of the fuselage. some debris may have drifted as much as 60 miles from the airport's last known location. the news only made worse as relatives found out while watching local news where bodies were shown without warning on live tv. airasia's ceo tony fernandes

called it heartbreaking. >> this is a horrible horrible experience. >> reporter: among the 162 passengers and crew on board, there were 17 children and 1 infant. 26-year-old tina marie widodo was a biology teacher. her father and boyfriend were overcome with grief. while families wrote, i hope this is just a nightmare that i can end by simply waking up. the pilot was captain irianto, a man with more than 20,000 hours in the cockpit. his daughter took to essential media during the searched ming with her dad to come home writing, papa come back. i still need you. return my papa to me. today his wife said i must be strong and tough and i'm here for their children and their future. still, some weren't ready to give up hope. this woman saying from the bottom of my heart, i want them to still be alive. as for that charter flight that airasia was going to give family members so that they could pray

for their loved ones over the last known location of the plane, that has been postponed, lester so that they can focus on the search. >> katy thanks. a lot of the questions about what happened to flight 8501 including how the crew planned to circumvent those storm cells will be more after the flight data boxes are recovered. tom costello. >> reporter: if flight 8501 is resting at the bottom of the java sea, a priority for search teams be finding the tail section that holds the plane's cockpit voice and flight data recorders. the flight was supposed to be at 32,000 feet flight aware shows it at 36 300. the pilot had asked to climb to 38,000 feet to avoid bad weather but air traffic control deny the request because of other air traffic in the area. those planes managed to navigate around the storm and land safely. but airasia may have been near

stall speed. the question -- why? >> whatever occurred occurred quickly and resulted in the crew not being able to successfully deal with it and as a result the airplane's at the bottom of the ocean. >> reporter: investigators will likely look at the plane's pitot tubes that help calculate its air speed. if they iced over in severe weather, the flight's computers may have given bad data confusing the pilots. that's what happened with air france 447. the pilots panicked grabbed the controls then stalled and crashed the plane into the atlantic. former ntsb board member -- >> if they just taken their hands off of it they would have come out the other side got their air speed indicators back and put it on autopilot and they would have been fine. >> reporter: investigators learned what happened only after retrieving the black boxes which took two years. search teams will begin listening for the pins coming from airasia's black boxes.

the u.s. navy already in the area is offering listening technology. >> once you can detect the sound, then you can try ankh u late and fix the location of those black boxes on the ocean floor then figure out how you're going to get them and recover them. >> reporter: we talked about the concern about the pitot tube icing event. heavy icing and hail at high altitude can pose a risk to the engines themselves. they'll be inspecting the flight data recorder looking for any signs of that and those engines if they're ever able to pull them off the floor of the sea. >> we're joined by our nbc news aviation analyst and a former ntsb investigator. greg a lot of the focus right now on whether this was a strug toll the end for the pilots to keep that plane in the air or if it broke up i recognize probably not enough wreckage to conclude that question right now, but is the fact that there was no mayday no declaration of an emergency, tell you anything? >> yes, lester it really does. it indicates that the pilots were consumed with either

maintaining or regaining control of the airplane and that that was their primary task and that was the center of their attention. and that the old adage in aviation is aviate navigate communicate. your primary responsibility the maintaining control of the airplane communicating what has happened and what you desire is the last thing on the priority list. >> tom mentioned this possibility of a pitot tube freezing up like we saw on flight 447. will this again focus questions on the amount of automation in today's airplanes? >> i think it will bring up a debate with regard to the actions that the pilot took or didn't take. it's all going to be dependent on what's on the flight data recorder. and if the airplane did get into some sort of unusual latitude that the pilot either lost control or couldn't regain control, there could be a debate about how much automation we depend on as pilots in flying in conditions where the airplane becomes upset and the recovery techniques that are used by crews. >> greg feith, good to have you with us tonight.

thank you. former president george h.w. bush is resting at home in texas after spending a week in the hospital. he was admitted last tuesday with shortness of breath and spent the christmas holiday under medical care. at age 90 he's our oldest living former president. one of the most powerful men in congress today said he made a regretful mistake when he spoke before white supremacist group more than a decade ago. congressman steve scalise of louisiana, the third ranking republican in the house, claims he did not know that the group stood for when he spoke at their gathering in 2002. it's only coming to light now after a blogger dug up old postings online. separately another republican new york congressman michael grimm announced he is resigning. this after grimm pleaded guilty a week ago to felony tax evasion. grimm had won re-election in november when the case was pending against him. some encouraging news tonight from the american cancer society. a new report says there's been a 22% drop in the death rate from cancer over the past two

decades, which means 1.5 million cancer deaths have been averted over that time. the report credits fewer americans smoking as well as medical advancement, but it also says we'll see over 1.6 million new cancer cases in the new year and close to 600,000 deaths. an alarming report starkly lays out the dangers faced day in and day out by those responsible for serving and protecting us. it shows an enormous jump from last year in the police killed in shooting incidents. the police advocacy group that put out this report fears that what it is seeing on the streets lately is having an influence. our report tonight from nbc's stephanie gosk. >> reporter: just this week two officers were caught in gunfire in los angeles, and in florida a gunman fired on two sheriff deputies sitting in their squad cars. the motives are still unknown. a report out today says 126 in law enforcement lost their lives on the job in 2014 with a 56%

increase in the number of police officers killed by gunfire in the last year. of those, 15 were killed in ambush attacks. the total number of deaths is still below the decade average, but the head of the law enforcement group that conducted the report is concerned a growing anti-government sentiment may be triggering attacks. there have been months of nationwide protests calling for police reform. after the deaths of unarmed blackmen in what some call persistent mistreatment by cops. are protests to blame for increased violence against police officers? >> no. these protests have been centered around respect for human life dignity for human life. >> reporter: but many in law enforcement worry about isolated messages like this one in new york earlier this month. >> what do we want? >> dead cops. >> when do we want it? >> now. >> reporter: some blame protests in part for the murder of two nypd officers. at the funeral for officer

rafael ramos, 19-year-old justin ramos wore his father's uniform, the same uniform that made his dad a target. >> any time i attend a police officer's funeral, i always pray that it will be the last. but i know it won't. >> reporter: that same day in florida, another teenager said good-bye to her father police officer charlie condeck. >> my dad died as a hero but he was my hero before he was any of yours. >> reporter: stark reminder of what police officers put on the line every day. stephanie gosk nbc news, new york. a frigid blast of arctic cold is descending on most of the nation and it is already putting the freeze on some new year's eve plans in many cities. dylan dreyer is out on rockefeller plaza with us for our forecast. >> good evening. it is going to be a very cold end to 2014. take a look the jetstream and see just how far south that cold air is stretching. we're going to be waking up to

lows tomorrow morning and wind chills 20 to 40 degrees below zero. austin texas, will top out at 42 degrees. they're even considering postponing outdoor new year's eve plans because of the cold. tomorrow night we're looking at most of the country below freezing 5 in denver 28 in times square for all the folks watching the ball drop. we'll even see snow across the southern rockies and 44 for a high in las vegas. in pasadena california home of the rose parade we could break a record morning low and temperatures wind chills throughout the parade will only be in the 20s. and speaking of wind the bay area in california is under a high wind warning through the day tomorrow we could see wind gusts as high as 65 miles per hour, even higher in the highest elevations than down in the valleys, lester. everyone will be bundled up for sure as we ring in the new year. >> dylan dreyer and friends on the plaza tonight.

that it wasn't going to work. but chantix helped me do it. along with support, chantix (varenicline) is proven to help people quit smoking. it gave me the power to overcome the urge to smoke. some people had changes in behavior, thinking or mood hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some people had seizures while taking chantix. if you have any of these stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse while taking chantix or history of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you develop these stop chantix and see your doctor right away as some can be life-threatening. tell your doctor if you have a history of heart or blood vessel problems or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while taking chantix. use caution when driving or operating machinery. common side effects include nausea trouble sleeping and unusual dreams. i'm a non-smoker. ask your doctor if chantix is right for you.

i recognize this may be hard to believe considering the cold that's gripping so many of us around the nation. maybe it will help if you think back to the summer when we were all cranking up the ac. because 2014 will go down as the warmest year around the globe in

recorded history. nbc's anne thompson explains. >> reporter: for many americans, 2014 will be remembered as the year of digging out. >> i'm done with winter. officially. >> reporter: beginning and ending under a pile of white. >> i'm ready to move. >> reporter: but for the planet as a whole, 2014 is set to be the warmest year on record. continuing a century-long trend from cooler than average temperatures in 1913 to a predominance of above average temperatures in 2013. this year's record fueled by the warming oceans with seven consecutive months of new high temperatures. while yearly changes may play a role noaa says the prime suspect is climate change. >> greenhouse gases warm the atmosphere. that atmospheric temperature increase then penetrates into the ocean as well. >> reporter: on land australia sweltered through its hottest spring on record with temperatures topping 100 degrees. researchers say this was europe's hottest year in 500

years. even siberia felt the heat. the coldest town in the world averaged a record 9.5 degrees in february. usually it's 51 below. all in stark contrast to much of the u.s. >> this year the west was very warm the central and eastern parts were average to below average. >> reporter: in fact january to november were the coldest in the lower 48 since 1997 despite record warmth in arizona and california making it a small cold spot in a record warm year. anne thompson nbc news new york. we're back in a moment with cars trapped under an avalanche of white in chicago, but we're not talking about snow. huh, fifteen minutes could save you fifteen percent or more on car insurance. yeah, everybody knows that. well, did you know that playing cards with kenny rogers gets old pretty fast? ♪ you got to know when to hold'em. ♪ ♪ know when to fold 'em. ♪ ♪ know when to walk away. ♪ ♪ know when to run. ♪

sousa says the president joked that these are the two most famous sets of ears in washington when he saw this shot of him standing next to the white house easter bunny. here he is holding a koala when he was in australia for the g-20 in november. this shot proves that no matter how powerful you are, you have to times get your hands dirty. this is the president swatting a fly with a rolled-up magazine in the oval office. no word if he was successful. a time when cars suffer salt damage but not like this. a wal collapsed at the morton salt building brought an avalanche of salt down on the acura dealership next door. fortunately no injuries reported. when we come back it's not a new idea. in fact it goes back thousands of years, but school leaders say it's turning their problem classrooms around.

we send our kids off to school each day so their minds can be filled with knowledge. but clearing the mind that's the practice one school district is preaching. it's taking time out of the day for meditation. and by looking inward these students are finding outward

success. the story tonight from nbc's cynthia mcfadden. >> reporter: at first glance visitacion valley school in san francisco looks like an ordinary chaotic middle school. but twice a day something out of the ordinary happens that has changed everything. it is the sound of silence. eight years ago in the heart of one of the city's poorest and most violent neighborhoods, the school was spiraling out of control. >> there would be fights here three to five times a week. the kids see guns on a daily basis. they see all sorts of weaponry. they have that baggage with them. >> reporter: desperate, the district tried a pioneering program called quiet time. >> ignore the sounds upstairs in the hallway. >> reporter: the idea teach students transcendental meditation and give them two 15-minute periods a day to close their eyes and let go of the stresses in their lives. >> so did you buy into this at

the beginning or were you a little bit like hold it a minute meditation? >> i thought it was a joke. i thought this was stuff that didn't work in the '70s so how will it work now. >> reporter: but four years later some startling results made the skeptical coach a true believer. a 79% decrease in suspensions. an increase in attendance to 98% and a clear rise in academic performance. more than 1500 students and 170 staffers have now been trained to meditation in four of the district schools. including burton high. once known as fight school. this is burton high today, where meditation has replaced mayhem. there are people who will say, hold it a second. you're taking a precious half an hour out of the school day. >> i actually was in the same boat and i was like there's no way i'm going to steal time from english instruction or math instruction in order to do that. >> reporter: instead he agreed to extend the school day. now the results are as dramatic

as in the middle school. a 75% reduction in suspensions and a move from the bottom of california's academic ladder to the upper middle rungs. school officials say that's because students now feel safe relaxed and ready to learn. >> it makes you more conscious of your actions. >> i brings you down to a calmness. >> reporter: before tobias started meditating he says he was an angry kid. >> i always want to fight everybody for some reason. >> reporter: you remember. >> yeah. >> reporter: did you see a change in him? >> yeah tremendously compared to from sixth grade to now. >> reporter: you can't change the violence and the stress that happens outside these walls. >> i cannot but i can help our students find ways to deal with the violence the trauma and the stress of everyday life. >> reporter: tools they can use with their eyes closed. cynthia mcfadden, nbc news san francisco. that's our broadcast for this monday night. thank you for being with us. i'm lester holt in for brian.
