A woman in a car was ramming a man on a motorcycle, chasing him down the streets of Chula Vista, California. A police drone flew after them, broadcasting a live video feed to officers' smartphones.All officers in the department had been out on other high-priority calls when they received the report of two people fighting -- so they deployed their newest emergency response tool. Thanks to the footage from the drone, when officers arrived on scene, they knew exactly where to find the woman and man, and what had happened moments beforehand.They arrested the woman for assault with a deadly weapon, but also found the man happened to be riding a stolen motorcycle. The theft was unrelated to the incident.This is how the Chula Vista Police Department has started using drones to respond to calls, as part of a Federal Aviation Administration program. While police departments have already used drones as part of investigations after a crime has occurred, this program sends a drone out ahead of officers while the crime may still be in progress; officers use that footage to decide how to approach the situation."It gives someone like myself, the Watch Commander, a front row seat to what's going on," said Lt. Christopher Kelly.In the six months the program has been active, drones have helped Chula Vista police make more than 56 arrests. For comparison, Chula Vista police made 6,027 arrests over the course of last year.Police say arrests are up since the drone program began in October compared to the same time period last year, but that it's too early to attribute the change to the drone program.Chula Vista Police Chief Roxana Kennedy said the drones had mostly been operating within a limited range of a mile radius around the station, while the whole city is 52 square miles. "That being said, the drone has effectively contributed to several arrests where it arrived on scene first and vectored officers to the suspect," she said.How the system worksDirected by an officer sitting in the basement of Chula Vista police headquarters, a drone launches from the rooftop.On the roof, another officer sets the geo-fence, a virtual geographic boundary set by GPS, to tell the drone where to go.The pilot on the roof can override the officer directing the drone from the basement if he sees an obstruction, like a flock of birds or manned aircraft, in the way.Federal law typically allows drones to only be flown within the operator's line of sight. The FAA's Integration Pilot Program is letting cities across the United States test flying drones longer and farther, for package delivery, agriculture operations, medical equipment delivery and public safety, among other uses. Along with the city of San Diego, the city of Chula Vista is focusing on the area of public safety operations.Using an off-the-shelf drone and software from a company called Cape, officers can direct the drone via computer from anywhere.Kennedy, the police chief, said the drone is not a replacement for police officers, but it is a tool to help improve the safety of both officers and citizens they're sworn to protect. "It's a game-changer for law enforcement," she said.While a 911 caller may be distraught and may give incomplete or inaccurate information, a drone can get there faster than a police car and zoom in for a closer look.Kennedy said that the zoom feature on the drone's camera allows officers to see a license plate from two miles away, and that kind of tool helps them make better informed decisions and plot a smarter strategy.She said she hopes it could help avoid deadly force incidents — giving officers a chance to assess a situation and to think about how to defuse it before rushing onto the scene."I think that this is so vital for us in law enforcement right now as we're under tremendous scrutiny," she said. The drones could give the officers "real-time information to determine whether somebody actually does have a weapon in their hand, is it not a weapon, is it a pencil, is it something different?"Privacy concerns"Just this morning we saw one come. Someone called about somebody in their yard, and the first thing we saw was the drone," said David Ward, who lives in the city.Some Chula Vista residents have questions about the drones overhead."It might help solve crimes. But I think drones are a little bit of a violation of privacy. Can they look in your window?" said Marie Paniagua.The police chief said the department has done a lot of work to get the community's buy-in."We have worked really hard to make sure that we have policies in place that we address those issues," Kennedy said. "We don't do random patrol with our drones. They're not utilized that way at all. They are not for surveillance. The only time a drone would be used for instance, a search warrant if it was approved through the judge and there was an actual search warrant."Ward said he wants to know whether citizens have a right to see the footage collected, "but I believe that they're doing it to protect people's safety," he said.Future of drone regulationKennedy said Chula Vista has the lowest staffed police department in San Diego County, with 242 sworn officers covering the 52-square-mile area.The eventual goal, she said, is to be able to at least get one drone over a scene within two minutes of a radio call, and to have the drones placed at police stations and fire stations around the city.Capt. Vern Sallee describes the project in three phases: crawl, walk, run."We're getting feedback from them (the FAA) as to what they need to have confidence in our systems, in our drones, to start changing the rules to better integrate drones into the national air space they control," Sallee said.And last month, Chula Vista police drones got clearance to fly farther.On March 15, the FAA granted Chula Vista PD the first-ever certificate of authorization with a "beyond visual line of sight" provision for an Integration Pilot Program participant that allows for proactive emergency response.That gives them a 40-mile flying radius, according to Cape -- and police say those longer drone flights have already started. 6135
American Airlines plans to cancel flights well into April because of the Boeing 737 Max grounding.American, the world's largest airline, said Sunday it is canceling about 90 flights a day out through April 24. Before Sunday's announcement, American had only canceled flights through March 28.The airline is hopeful that that the 737 Max planes will be flying again soon, but said it is canceling flights about a month out as it waits for word from the Federal Aviation Administration."Canceling in advance provides additional availability and rebooking options for our customers," said the statement from American.The global fleet of 371 of the 737 Max jets was grounded indefinitely on March 13 after two of the planes had fatal crashes. A Lion Air flight crashed in October and an Ethiopian Airlines flight crashed on March 10.The causes of the crashes have yet to be determined but the focus has been on an automatic safety feature which may have forced the nose of each plane lower when it incorrectly believed the plane was in danger of going into a stall.Boeing and the FAA said they are working on an upgrade of its software to deal with that safety feature. Boeing said at the time of the grounding that it expected that update to be available "within weeks."American has 24 of the 737 Max 8 jets. But not every flight which had been scheduled to have a 737 Max has been canceled. American said it has rearranged its schedule to use other aircraft to complete some of those flights."We have balanced [cancellations] across our system," said the airline. It said both international and domestic flights are affected. "We will vary by day as we look to impact the fewest number of customers."American operates 3,300 flights its mainline system daily on average, and another 3,400 through regional carriers and partner airlines.Other carriers are not canceling nearly that far out.Southwest Airlines, which has 34 737 Max jets, said it is only canceling five days out at this point. It said it is also trying to rework the schedule to affect the fewest possible number of customers. 2099

A Spanish man spent his summer vacation paddling his way from the west coast of the U.S. across the Pacific Ocean to Hawaii.It took Antonio de la Rosa 76 days to paddle some 2,500 miles while standing on a submarine-shaped craft. He had planned to make the trip in 70 days, but suspects he drifted too far north at one point during his journey.He celebrated his 50th birthday at sea and arrived Saturday in Honolulu.de la Rosa said Monday that he's feeling a bit tired.He paddled eight-to-10 hours daily and slept every night. But he was always tired because he woke up hourly to check on his gear.In addition to a sleeping cabin, de la Rosa's boat included computers and GPS systems that ran on solar energy created by panels on the roof. However, the boat was only moved by wind, ocean currents and de la Rosa himself.He believes no one has ever done what he accomplished.In Spain, he runs an adventure tourism business and says he enjoys adventurous vacations. 976
A Pennsylvania police department is warning parents to be extra vigilant this upcoming Halloween after finding a marijuana edible that looks a lot like a popular candy.The Johnstown Police Department posted on Facebook that they found candy bearing resemblance to the "Nerds Rope" when executing a search warrant in Stonycreek Township, Pennsylvania.The marijuana edible looks like the traditional Nerds candy but contains 400 mg of THC. "During this Halloween, we urge parents to be ever vigilant in checking their children’s candy before allowing them to consume those treats," police said on Facebook.A marijuana edible, often shortened to just "edible," is a food or drink item that contains marijuana. Medical marijuana is legal in Pennsylvania for pertinent medical conditions, but it's not legal for recreational use. While police departments often issue these warnings around Halloween, it's worth nothing that edibles are often labeled as containing marijuana on the package. There are a few documented cases of children ingesting marijuana edibles on or around Halloween, such as the 1106
All unaccompanied migrant children housed at a controversial south Florida facility have been removed, the federal Administration for Children and Families said Saturday.The Homestead facility, south of Miami, sheltered about 14,300 children since it was activated in March 2018 to house unaccompanied minors apprehended by the US Department of Homeland Security, officials said.The facility came under fire for what immigration activists described as unsuitable conditions for children. It also became a popular stop for Democratic presidential candidates and protesters clamoring for its closure.As of Saturday, no children were housed at the temporary facility, Evelyn Stauffer, a spokeswoman with Administration for Children and Families (ACF), said in a statement. Their relocation was first reported by the Miami Herald.Stauffer said the children housed at Homestead had been either reunified with a sponsor or have transferred to state facilities.ACF is a division of the US Department of Health and Human Services, which is responsible for the care and custody of children 17 years old and under who are unaccompanied and have no lawful immigration status.The Homestead facility will remain open, however, reducing bed capacity from 2,700 beds to 1,200."We anticipate an uptick in the number of referrals made to HHS this fall, based on historical trends," Stauffer said in the statement.Immigration activists had for months pushed for the closure of the sprawling compound, which is tucked behind a chain link fence.In June, Massachusetts Sen. Elizabeth Warren attempted to visit the complex but said she was not allowed to enter. After standing atop a ladder with a hat and sunglasses to wave to children behind the fence, she said they were "being marched like little soldiers, like little prisoners ... This is not what we should be doing as a country."Other presidential candidates followed.Immigration advocates complained the minors were not allowed to hug and had limited access to phones to call their parents.The Homestead facility is 2065
