Two politicians, a staff member and a helicopter pilot, miraculously survived when the aircraft flew into power lines, crashed into the ground and burst into flames.
The stunning video captures the moment when a silver helicopter carrying Brazilian MP Hercílio Araújo Diniz and Governador Valadares Deputy Mayor David Barroso drifts slowly into a power cord.
Video of the crash was recorded by witnesses on the ground, and onlookers can hear the helicopter panting in horror as it loses its composure and dives into the ground below, where it catches fire.
All four people on board suffered minor injuries, according to the Brazilian state of Minas Gerais. They were taken to a nearby hospital for treatment.
After the accident, power was cut off to the municipalities of Sobralia and Fernández-Tourinho, according to local reports.
