"Particularly since Sept. 11, any type of interference with a United States civil aircraft is dealt with very harshly," Booth said.
Under Florida state law shooting at an aircraft is a second-degree felony. Federally, if convicted, the crime could carry a punishment of up to life in prison.
Booth said he isn't sure if the plane was target or just happened to fly into the path of a stray bullet. But either way, he said at that height, hitting it is a one-in-a-million chance.
Hill believes people need to be careful.
"There's more of a chance that it was just a coincidence than an actual intentional shooting," said Hill. "Because you don't know what's up there, and where it's going to go after you shoot."
Celebratory gunfire is a continuing issue for law enforcement agencies. On the ground in downtown Jacksonville New Year's Eve, an 8-year-old boy was hit by a bullet waiting on the Southbank Riverwalk to watch the fireworks display.
The boy told his dad something hit his foot and police say a bullet was found in the child's shoe.
Celebratory gunfire has been deadly many times in nationally, including the death of an 8-year-old girl in Maryland this New Year's.
Channel 4 found four other instances where celebratory gunfire has turned deadly in the past 20 years.
Anyone with information about who's responsible for the shootings is asked to call the Jacksonville Sheriff's Office at 904-630-0500 or Crime Stoppers at 866-845-TIPS.
