Progress in covering large events with aerial drones, especially protests, has been led almost exclusively by political activists. The most recent effort by activists to use drones document the scale of anti-government demonstrations comes from Argentina, where the “8N” demonstration on Thursday, November 8.
That day, some 30,000 Argentinians protested economic conditions, government corruption and the fear that President Cristina Fernandez will attempt to end her term limit.
According to the group El Cipayo Argentino, the government had closed down the airspace ahead of the protest, and did not allow news helicopters to cover the event. So the group came up with a low-budget workaround: they built their own aerial drone to provide coverage from the sky.
As you can hear from the video, the camera attached to the drone picked up a great deal of propeller and motor noise. The fact that protestors can be heard above the din of the whirring motors speaks volumes.
Al Jazeera has a write up about the protest and the activists behind the drone here.
