Delta Flight 126 had left the gate at Kennedy Airport around 8 p.m. Thursday, but returned about an hour later after a passenger reported finding the wires. The 206 passengers were evacuated.
The NYPD says the wires were determined to be non-explosive but apparently didn't belong to the plane.
Delta spokeswoman Sarah Lora says Flight 126 departed for Madrid at 3:43 a.m. Friday.
She says the flight had returned to JFK "out of an abundance of caution."
