A drone hovering over a Memorial Day parade in Marblehead in the US state of Massachusetts struck a building and fell on two spectators, injuring them.
Scot Yount suffered a small gash in the back of the neck when he and another woman spectator were hit by the out-of- control drone yesterday.
"I heard people yell and felt this clunk on my head and the back of my neck. I realised I just got hit by the thing," Yount told CBS Boston.
Neither person was seriously injured and the drone operator, who was not identified, apologised.
"It could have been a disaster," the drone's owner said.
The man assured the police that he would not operate the drone over Marblehead again, and no charges will be filed.
Yount was holding his 1-year-old daughter only moments before and said the incident could have been much worse.
"That guy has to think about where he flies the thing and what could have happened if he hit my daughter," Yount said. "I'd be pretty upset."
The US Federal Aviation Adminstration safety guidelines suggest not flying the aircraft near people.
Yount, a a former television news journalist, said he has followed some of the controversy about drone regulations.
He said his close call raises big questions about the tiny aircraft, and believes there should be some license required before people fly drones over crowds of people.
