The Federal Aviation Authority in the US is looking into a video showing a near miss between a helicopter and an unmanned drone in Niagara Falls.
The footage appears to be from last year, and the pilot admitted to making a mistake writing, 'I was terrified. I couldn't imagine crashing into a helicopter, possibly causing it to crash and kill someone. I learned my lesson."
The original video has been removed, but copies remain available on Youtube.
Drone flights in the area are prohibited by authorities on both sides of the border.
