Several drones malfunctioned at a planned light show in Orlando, causing them to fall on the ground and into the crowd, where they struck a 7-year-old boy.
The child sustained severe injuries, including chest trauma, and is presently undergoing treatment that includes heart surgery.
The drone light show was managed by Sky Elements, a prominent drone light show company known for Guinness World Records.
The child's family has established a GoFundMe to assist them, which has so far earned them over $6,000.
Sky Elements is working with FAA and city officials to establish the reason for the accident.
The other planned drone light show at Lake Eola was cancelled.
Sky Elements is organizing another drone light display in Orlando, from Christmas to New Year's Eve, at the Orlando World Center Marriott.
The FAA is recently investigating more than 5,000 reports of drone sightings, primarily in New Jersey, while deployed detection technology.
There is no evidence of lawless or malicious drone activity, according to the FAA.
The Lake Eola incident rekindled concerns about drone safety in potentially packed environments, even though drones are believed to be less dangerous than fireworks.
