CARLSBAD, Calif. (KGTV) -- Starting in January, San Diegans with a long commute can choose to ditch the traffic and fly to work thanks to a start-up service co-founded by a UC San Diego graduate.FLOAT, which stands for Fly Over All Traffic, is a commuter air service that will operate a fleet of nine-passenger planes at small airports throughout Southern California. Like van pools, routes will be determined by customer demand. There is already interest in service out of McClellan-Palomar Airport in Carlsbad, the company reports. Other San Diego airports like Montgomery-Gibbs in Kearny Mesa and Brown Field in South Bay could be added, said co-founder and CEO Arnel Guiang.RELATED: Making It in San Diego: Some San Diegans commuting three hours to, from work"FLOAT is shattering the myth that sitting in hours of traffic every day is a necessary and unavoidable way of life in Southern California,” said Guiang.A base membership will cost ,250 per month for flights five days a week, he said. That means each leg of the commute will cost about .Guiang, a UCSD computer engineering graduate, said he came up with the idea for FLOAT while working at Northrop Grumman in Los Angeles County, where his commute took two to three hours a day.RELATED: San Diego commuters spending 64 hours per year stuck in trafficOne day, Guiang said a coworker offered to fly him to work in a private plane, shaving his commute to about 20 minutes.“With the high cost of living, more Southern Californians are finding nice homes at attractive prices in the suburbs outside of thriving business locations, which leads people to lengthier commutes,” Guiang said. “Carpool and vanpool options are only shaving a few minutes off these commutes, and these lengthy commutes are cutting into people’s quality of life.”The service is targeting so-called “super commuters,” those with commutes of 90 minutes or more each way. There are nearly 26,000 super commuters in San Diego alone.RELATED: Check 10News Traffic reportsCustomers will be able to walk onto a plane in minutes using an app, without security checks by the TSA, Guiang said.FLOAT will start with three planes at first, and the company says the idea is taking off: more than 700 people have signed up so far.Customers can request a route here. 2295

CAPE CANAVERAL, Fla. (AP) — The spacecraft team that brought us close-ups of Pluto will ring in the new year by exploring an even more distant and mysterious world.NASA's New Horizons spacecraft will zip past the scrawny, icy object nicknamed Ultima Thule (TOO-lee) soon after the stroke of midnight.One billion miles beyond Pluto and an astounding 4 billion miles from Earth (1.6 billion kilometers and 6.4 billion kilometers), Ultima Thule will be the farthest world ever explored by humankind. That's what makes this deep-freeze target so enticing; it's a preserved relic dating all the way back to our solar system's origin 4.5 billion years ago. No spacecraft has visited anything so primitive."What could be more exciting than that?" said project scientist Hal Weaver of Johns Hopkins University, part of the New Horizons team.Lead scientist Alan Stern of Southwest Research Institute in Boulder, Colorado, expects the New Year's encounter to be riskier and more difficult than the rendezvous with Pluto: The spacecraft is older, the target is smaller, the flyby is closer and the distance from us is greater.NEW HORIZONSNASA launched the spacecraft in 2006; it's about the size of a baby grand piano. It flew past Pluto in 2015, providing the first close-up views of the dwarf planet. With the wildly successful flyby behind them, mission planners won an extension from NASA and set their sights on a destination deep inside the Kuiper Belt. As distant as it is, Pluto is barely in the Kuiper Belt, the so-called Twilight Zone stretching beyond Neptune. Ultima Thule is in the Twilight Zone's heart.ULTIMA THULEThis Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote. In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world. When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.ARE WE THERE YET?New Horizons will make its closest approach in the wee hours of Jan. 1 — 12:33 a.m. EST. The spacecraft will zoom within 2,200 miles (3,500 kilometers) of Ultima Thule, its seven science instruments going full blast. The coast should be clear: Scientists have yet to find any rings or moons around it that could batter the spacecraft. New Horizons hurtles through space at 31,500 mph (50,700 kph), and even something as minuscule as a grain of rice could demolish it. "There's some danger and some suspense," Stern said at a fall meeting of astronomers. It will take about 10 hours to get confirmation that the spacecraft completed — and survived — the encounter.POSSIBLY TWINSScientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, it's likely 20 miles (32 kilometers) long at most. Envision a baked potato. "Cucumber, whatever. Pick your favorite vegetable," said astronomer Carey Lisse of Johns Hopkins. It could even be two bodies connected by a neck. If twins, each could be 9 miles to 12 miles (15 kilometers to 20 kilometers) in diameter.MAPPING MISSONScientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth. As for color, Ultima Thule should be darker than coal, burned by eons of cosmic rays, with a reddish hue. Nothing is certain, though, including its orbit, so big that it takes almost 300 of our Earth years to circle the sun. Scientists say they know just enough about the orbit to intercept it.COMPARING FLYBYSNew Horizons will get considerably closer to Ultima Thule than it did to Pluto: 2,220 miles versus 7,770 miles (3,500 kilometers vs. 12,500 kilometers). At the same time, Ultima Thule is 100 times smaller than Pluto and therefore harder to track, making everything more challenging. It took 4 ? hours, each way, for flight controllers at Johns Hopkins' Applied Physics Lab in Laurel, Maryland, to get a message to or from New Horizons at Pluto. Compare that with more than six hours at Ultima Thule.WHAT'S NEXTIt will take almost two years for New Horizons to beam back all its data on Ultima Thule. A flyby of an even more distant world could be in the offing in the 2020s, if NASA approves another mission extension and the spacecraft remains healthy. At the very least, the nuclear-powered New Horizons will continue to observe objects from afar, as it pushes deeper into the Kuiper Belt. There are countless objects out there, waiting to be explored. 4591

The vehicle overturned and the man was thrown from the SUV.CHP, Camp Pendleton Fire Department, and North County Transit District responded to the scene, but the man died at the scene. He was not immediately identified.Investigators said they don't believe alcohol or drugs were a factor in the crash, and are still looking into the crash. 755

  

CAPE CANAVERAL, Fla. — The biggest, most sophisticated Mars rover ever built is on its way to the red planet. NASA's Perseverance blasted off from Cape Canaveral, Florida, atop an Atlas V rocket Thursday morning. It's the first step in an ambitious project to bring the first Martian rock samples back to Earth to be analyzed for evidence of ancient life. The six-wheeled rover will drill down and collect tiny geological samples that will eventually be retrieved and brought home in about a decade. China and the United Arab Emirates also have spacecraft en route to Mars, after launching last week. They are all due to arrive at Mars in February. 656

  

CHARLOTTE COUNTY, Fla. -- A Polk County, Florida man is pleading for a thief to return a sentimental wedding gift that was stolen out of a family member's truck in Port Charlotte.Boomer Bass left for a fishing trip on Little Gasparilla Island last week, and thought it was best to leave his Springfield 1911 Range Officer Gun with a family member, rather than bring it with him.On April 19th, Bass's mother reported that the gun was stolen out of his truck in the Water's Edge neighborhood in Englewood. The gun holds sentimental value to Bass. "I had a gun very similar to this one when I was younger," he said. "I sold it to help a friend of mine out, and I really regretted selling that gun." With this in mind, his wife, Stefanie, made the decision to buy him that same gun on the morning of their wedding. They married in October of last year. "She went and bought that gun for me and gave it to me that night at our wedding reception, actually," Bass said. "I think the gun signified, really, that she understood the generosity I showed when I was younger, and she wanted to show me she would be the kind of wife that would do those things for me."Stealing a gun is a felony in the state of Florida. However, Bass says if the thief wants to return his gun, he would accept it with no questions asked. "Hopefully, you feel like you made a mistake. I will not prosecute, I will not pursue any legal action. All I want is this gun back," he said. Bass said he is willing to pay the retail price for a brand new gun if his is returned safely. It is a Springfield 1911 Range Officer with wood grips, night sights, blued finish, serial # NM502637. "I'm begging you...to anyone else, this is just a gun," he said. "But to me, it means more than I can even put into words."If you have any information that could help lead Bass to his sentimental wedding gift, or you are in possession of it, he asks that you contact him directly on Facebook at Boomer Bass.  2039
