 Next time — who knows? 
  
 Rattled New Yorkers questioned how the NYPD could let a nimble pack of late-night intruders scale the landmark Brooklyn Bridge to hang two enormous, bleached-white American flags. 
  
 “Aren’t there security cameras everywhere?” asked an angry Francisco Correa, 29, of Brooklyn. “How did no one see this? This bridge is the key to our city. That shouldn’t have happened.”

 Cops were left scratching their heads and studying videotape after the trespassers reached the top of the iconic span’s 276-foot towers early Tuesday without anyone noticing. 
  
 They even used aluminum roasting pans fit for a Thanksgiving turkey to cover the floodlights illuminating the flags so they could work under cover of darkness. 
  
 “To be clear, we’re certainly concerned about it,” said John Miller, the NYPD’s anti-terrorism czar. “And certainly, as Commissioner (Bill) Bratton said, we are not happy about it.” 
  
 “If they had brought a bomb up there, it would have been over,” said a high-ranking police source. “If they were able to bring something large enough to cover the lights, then they would have been able to bring some kind of explosive up there.” 
  
 The furtive flag swap came within nine months of two security breaches at 1 World Trade Center: A 16-year-old boy who slipped past authorities and four daredevils who skydived from the top. 
  
 The 131-year-old bridge is considered a high-profile terrorist target, and it has two marked NYPD police cars assigned to either side of it.

 Security also includes cameras installed at undisclosed points along the bridge — although the video feed didn’t set off any alarms in the Tuesday morning darkness. 
  
 Citing security concerns, the NYPD would not say how many cameras are installed on the bridge. 
  
 The lights illuminating the Brooklyn side tower went dark first around 3:30 a.m., covered with an aluminum pan. The vandals used zip ties to keep the pan in place.

 Thirteen minutes later, the process was repeated on the soon-darkened Manhattan tower. The coordinated effort meant that it was at least a two-person job. 
  
 When the sun came up, construction workers spotted the white flags flapping in the breeze. Each was a 20-by-11-foot commercially available American flag bleached white. 
  
 Miller joked that the culprit was “Betsy Ross’ long-lost nephew doing extensive work.” The perpetrators likely had experience as climbers, construction workers or both.

 Brooklyn Borough President Eric Adams, whose office offered a $5,000 reward in the case, said there is nothing funny at all about the case. 
  
 “If flying a white flag atop the Brooklyn Bridge is someone’s idea of a joke, I’m not laughing,” he said. 
  
 As the day went on, nobody claimed responsibility for the bizarre banner swap, and the NYPD acknowledged it was stumped as to a motive. 
  
 “There’s no particular nexus to terrorism or politics,” said Miller. “It might be some kind of art project or statement. But we are not sure what that statement is.” 
  
 Miller said the size of the pans and the ability of the intruders to get past a locked gate gave “some indication of a good deal of pre-planning.” 
  
 Cops hoped to track down and interview five people seen on video crossing the bridge at 3:10 a.m.

 Construction worker Donald Mitchell, 37, said his first thought was terrorism when he spied the American flags bleached completely white. 
  
 “You could still see the stars and stripes,” said Mitchell, who was working on the bridge. “My first reaction was, ‘This is where you land the plane. X marks the spot.’ It was really scary.” 
  
 The stolen red, white and blue flags hung on the bridge are 12-by-18-foot banners installed by specially trained workers from atop a precarious perch above the East River. 
  
 The flags couldn’t have been removed and replaced without someone climbing up to the platform.

 The stolen flags were hung July 10, the day of FDNY Lt. Gordon Matthew Ambelas’ funeral after he died in a Brooklyn high-rise fire. 
  
 “I’m so angry I can’t tell you what I want to say,” steamed Cesar Pazmino, who started hanging the bridge flags 21 years ago. “It’s senseless. Whoever did this should be punished to the fullest extent of the law.” 
  
 Workers began taking down the white banners around 11 a.m. after police crime scene investigators determined there was no bomb or any notes left with the flags, cops said.

 rparascandola@nydailynews.com ||||| NEW YORK (AP) — Police are searching for four or five people they believe scaled to the top of the Brooklyn Bridge's two towers in the dead of night, disabled lights illuminating two large American flags and then replaced the flags with bleached-white ones.

 The security breach at one of the city's most secured landmarks didn't appear to be the work of terrorists or even a political statement, said the police department's deputy commissioner for counterterrorism and intelligence, but was likely done by people familiar with climbing or bridgework who may even have scaled the bridge before. 
  
 "We don't take these things lightly, or as a joke, or as art or within the realm of speech," John Miller said. "These are issues of trespass — they put themselves in danger, they put others in danger — and that's why we investigate it." 
  
 Video footage of the security breach shows the unidentified people walking on the bridge's footpath at about 3:10 a.m., and 20 minutes later the light on the bridge's Brooklyn tower flickers and goes dark, Miller said. The same thing happens about 12 minutes later on the Manhattan tower, he said. 
  
 Locked gates midway up the main cables leading to the tops of the towers didn't appear to have been tampered with, suggesting the climbers scaled them to reach the top, Miller said. 
  
 Two police cars sit at either end of the bridge, which stretches the East River connecting lower Manhattan and Brooklyn, and are fed real-time security camera footage trained on areas affecting the structural integrity of the bridge, Miller said, but those cameras didn't capture the flag bandits. 
  
 At about 5:30 a.m., construction workers noticed the white flags, apparently American flags about 20 feet by 11 feet and perhaps commercial grade, with faded stars and stripes, police said. Police removed the white flags just before noon. 
  
 The flags fly from above the pillars year-round and are replaced by transportation workers when they become frayed about every two months, police said. They are lit from the bottom by a lamp at the base of each tower at night — lights that were covered by aluminum foil cooking sheets secured with zip ties, Miller said. 
  
 More than 120,000 vehicles, 4,000 pedestrians and 3,100 bicyclists cross the Brooklyn Bridge every day, said the city's Department of Transportation, which maintains it. 
  
 Tourist Johan Lund, from Stockholm, Sweden, crossed the bridge Tuesday and did a double take when he noticed the white flags flapping in the wind. 
  
 "Wasn't there an American flag there yesterday?" he said to himself. 
  
 High-profile breaches have been made before. 
  
 In April, a street artist who filmed his effort scaling the Ed Koch-Queensboro Bridge as part of an art installation was arrested on criminal trespass and other charges. And in March, four skydiving enthusiasts were charged with reckless endangerment for sneaking into 1 World Trade Center, the nation's tallest building, months earlier and filming their jump from atop it. |||||
Apparently, all you need to orchestrate a prank on the Brooklyn Bridge are aluminum roasting pans and some mad climbing skills. Police say a small group of intruders used the pans to cover floodlights on the bridge's two towers before they hoisted two bleached-white US flags overnight Monday, the AP reports. Authorities say they're looking for four to five people—some of whom likely have construction or bridge work experience—seen in security footage walking on the footpath of the bridge around 3am. Police believe they scaled the main cables leading to the towers, thereby avoiding locked gates. A city worker tells NBC New York that the feat likely took two hours. The actual flag-replacement wasn’t captured by security cameras, and officers in two police cars at either end of the bridge noticed nothing amiss. “To be clear, we’re certainly concerned about it,” the NYPD’s anti-terrorism czar tells the Daily News. No motive is known, and police are scouring social media for clues. (This is the third security breach in New York City in recent months, including these parachuters and this teen.)
