In the wee hours of Tuesday morning, a NYPD helicopter made an emergency landing in Prospect Park. Needless to say, it was a very strange sight: The Daily News spoke to a dog walker who lives nearby and she said, "Most of the people thought it was for a movie because so many movies are filming in Park Slope right now. [It was] like having a giant SUV with mechanics under there trying to get the engine going." The helicopter eventually took off at 8:45 a.m. yesterday, after getting a once-over from a technical crew and after spectators made jokes about doughnut runs. The News says this is the second emergency landing in three days for the chopper—"The same helicopter - N315PD - made an unexpected landing on the Metropolitan Oval Soccer Field in Maspeth, Queens, just before 3 a.m. Saturday"—and both times, it was due to a "faulty indicator light." Apparently the patrol chopper is supposed to be replaced next year. After the jump, a video about the NYPD's aviation unit:
