Several North Jersey residents within eyesight and hearing range of the Hudson River and Newark Airport area caught a glimpse of four fighter jets roaring through the skies on Sunday. The appearance of the military planes prompted an outpouring of inquisition on social media, with one question on local residents' minds: "What the heck was all that craziness?"

Here was the jets' destination: a sporting event in Queens, NY. The U.S. Air Force jets were headed to a flyover at the men's final of the U.S. Open at the USTA Billie Jean King National Tennis Center for a match between Rafael Nadal and Kevin Anderson, and passed over the Hudson River and Liberty Island on their way, the New York Police Department told the Armonk Daily Voice.

The planes eventually landed at Newark Liberty International Airport, the report stated. The U.S. Open posted a video of the flyover on YouTube, identifying the planes as "four F-15E Strike Eagles from the 334th Fighter Squadron."
