Drone Knocks Woman Unconscious at Seattle Pride Parade
A 2-pound drone, which costs about $1,200, crashed into a building during Sunday's festivities and fell into the crowd, striking a young woman and knocking her unconscious. Authorities around the world are struggling with how to keep people safe with unmanned aircraft buzzing around overhead. With an increasing number of drones taking to the sky, the number of incidents are likely to increase over the next few years.
For one woman, Sunday's Pride parade in Seattle was a real knockout.

A 2-pound drone, which costs about $1,200, crashed into a building during Sunday's festivities and fell into the crowd, striking the unidentified 25-year-old woman in the head, Seattle police said Monday.

Her boyfriend caught her as she fell, and an off-duty firefighter treated the woman until police arrived.

Det. Patrick Michaud, a spokesman for the Seattle police, told NBC News the collision left the woman with "not a gentle concussion."

Police said they're seeking the drone's pilot, described as an unshaven white man in his 20s with "a noticeable tattoo of a woman somewhere on his body."

Authorities around the world are struggling with how to keep people safe with unmanned aircraft buzzing around overhead.

Last year, a drone fell from the sky during a triathlon in western Australia, injuring a runner.

Also last year, Seattle police questioned an Amazon employee after sightseers at the Space Needle saw a small quadrocopter buzz the landmark's observation deck, with some saying it had actually struck the window.

And earlier this month, singer Enrique Iglesias underwent surgery for a serious injury to his hand, caused when he reached out for a drone during a concert in Tijuana, Mexico.
