The Record of Woodland Park reports that 60-year-old Warren Saunders of Westwood entered into the plea agreement Monday with the Bergen County Prosecutor's Office.
He pleaded guilty to dropping objects from an aircraft in a populated area. He'll write a letter to the town's mayor apologizing.
Saunders said he did the drop over the Westwood Middle School athletic fields on Oct. 13 as a test run for a streamer drop he planned to do at a high school football game.
People on a nearby soccer field called police, prompting a large law enforcement response.
