Input: Consider Input: (CNN) -- Champions League holders Barcelona survived a scare in Germany on Tuesday evening as Zlatan Ibrahimovic's second-half equalizer earned them a 1-1 last 16 first leg draw against Stuttgart. The Catalan giants failed to produce the free-flowing football that has become their trademark under coach Pep Guardiola and they fell behind in the 25th minute. Stuttgart had warmed up for the match by hitting five goals past Cologne at the weekend, with striker Cacau helping himself to four of them. And the Brazilian-born forward maintained that form by opening the scoring here, powerfully heading home Timo Gebhart's cross. The home side had chances to double their lead before the break, with only goalkeeper Victor Valdes depriving Cacau of a second -- although Lionel Messi did strike the post with a long-range effort for the visitors. However, Barca regrouped after the break and levelled just seven minutes into the second period, when Swedish striker Ibrahimovic was on hand to finish from Gerard Pique's nod down. The result means Barcelona will be strong favorites to reach the quarterfinals when the teams meet again at the Nou Camp in a fortnight's time. Meanwhile, in the night's other match, Bordeaux look well set to reach the quarterfinals after a narrow 1-0 victory against Olympiacos in Athens. Laurent Blanc's side are unbeaten in the competition this season and look genuine contenders to win the trophy after Michael Ciani nodded home Yoann's Gourcouff's free-kick from close range on the stroke of half time. In the only Europa League match played in Tuesday, Portuguese giants Benfica cruised into the last 16 after thrashing Hertha Berlin 4-0 for a 5-1 aggregate victory. Two goals from oscar Cardozo and one apiece from Pablo Aimar and Javi Garcia ensured Benfica's smooth progress, where they will now face either Marseille or FC Copenhagen.

Input: Consider Input: (CNN) -- After nearly 40 years of recorded increases, the number of immigrants living in the United States remained flat between 2007 and 2008, recent statistics released by the U.S. Census Bureau show. The number of naturalized citizens in the U.S. increased, partly attributed to voter drives for the 2008 election. According to the Census Bureau's American Community Survey, the U.S. foreign-born population represented about 12.5 percent of the population in 2008, down from 12.6 percent in 2007. Taking into account the margin of error, it was possible that the immigrant population remained even. "Between '07 and '08 there really wasn't that much of a change," said Elizabeth Grieco, chief of immigration statistics staff at the Census Bureau. But given the steep upward trend in the foreign-born population since 1970, no change is big news. The American Community Survey collects data from about 3 million addresses each year, and provides one of the most complete pictures of the population, according to the bureau. The survey doesn't give a reason for the leveling off, but experts pointed to the economic downturn and the resulting high unemployment as factors behind the shift. "The recession has had a significant effect on immigrants' decisions on whether to come to the U.S.," said Michelle Mittelstadt, director of communications at the nonpartisan Migration Policy Institute. Would-be unauthorized immigrants and legal temporary workers are mostly the ones who have decided to stay put in their home countries for now, Mittelstadt said. The largest declines in the foreign-born population were in states that were hardest hit by the recession, including California, Florida and Arizona. Mittelstadt noted, however, that those immigrants already in the United States appear to be staying. A recent study by the Pew Hispanic Center concluded that emigration from Mexico, the largest source of immigrants to the United States, slowed at least 40 percent between mid-decade and 2008, based on national population surveys in the United States and Mexico, as well as Border Patrol apprehension figures. The Mexican-born population in the United States dropped by about 300,000 between 2007 and 2008, according to census data. The new Census statistics show that for the first time since the American Community Survey was fully implemented in 2005, the number of noncitizens decreased, Grieco said. There were about 21.6 million noncitizens in 2008, down from 21.9 million in 2007. The label noncitizens includes both legal residents and illegal immigrants. Along with the decline in the noncitizen population, however, there was a notable increase in the number of naturalized citizens, Grieco said. The number of individuals who are naturalized citizens increased to 43 percent of the foreign-born population in 2008 from 42.5 percent in 2007. The Census survey matches reports from the Department of Homeland Security on the rise of naturalization applications. "Naturalizations grew at a record pace between 2006 and 2008, with a total of 2.4 million immigrants becoming new citizens in the United States," according to a DHS statement. A significant fee increase imposed in 2007 for naturalization applications and an awareness of citizenship brought on during voter registration drives for the 2008 election help explain the increase, Mittelstadt said.

Input: Consider Input: (CNN) -- Investigators now say that, according to automated electronic connections attempts by the ACARS data reporting system of Malaysia Flight 370, the airplane flew far to the west, in an entirely different direction than it should have been heading as per its original flight-planned route, which was to the north. The 90-degree turn to the west might have been purely random if entered by a nonpilot or inexpert pilot who knew simply how to turn a single knob (called the heading bug) that could command the autopilot to make a turn to a new heading (or direction). There is strong evidence that this is not what happened. Investigators now believe, according to news reports, that after its transponder and ACARS radio were turned off, turns were initiated at GPS waypoints. These waypoints are essentially virtual checkpoints in the sky, defining markers charted by airspace regulators that create pathways in the air that airplanes follow to keep safely separated from each other. The waypoints are defined by an exact latitude and longitude and can be located by a number of the airplane's various navigators, including GPS. If the reports of the flight path are true, it is not a route that could happen by accident. There are two ways the 777-200 could have flown on this path. After passing one waypoint, it could have been directed to fly to the next waypoint by a pilot turning the heading knob toward that exact place, a process that would require some piloting expertise. This would be very unusual, and a novice or pilot without much flying experience on this plane would not know to make these kinds of inputs or have any conceivable reason to do so. The almost certain explanation would be that these waypoints were programmed into the flight management system of the 777-200, a task that would have been beyond the abilities of anyone but a professional pilot. The autopilot follows the course put into the flight management system by the pilots. That is, when the autopilot is not being manually controlled instead. The manual control part is easy. You turn a knob and the airplane goes where you ask it to. The flight management system part is very complicated. I am a commercial pilot, and I have done some training on the Boeing 777. Even after a few hours of professional instruction I would have been unable to program the flight management system to command the autopilot to fly the flight plan that Flight 370 reportedly flew. This leaves us with one of two possible conclusions. Either the flight was commandeered by a group with at least one professionally trained pilot among them or one of the pilots in control programmed the new off-route flight plan into the flight management system. The latter would be far more likely. When terrorists hijacked the airplanes that were flown into the World Trade Center towers and the Pentagon, they flew the airplanes by hand and those hijackers had trained for months with that exact mission in mind. In the case of Flight 370, it would almost certainly have remained on autopilot, which would have dutifully followed the flight plan in the flight management system. That flight plan was quite possibly entered for some mysterious reason by a trained pilot. The opinions expressed in this commentary are solely those of Robert Goyer.
