On Tuesday, a Russian fighter collided with a US Reaper drone, forcing it down into the Black Sea. A US European Command statement said the collision happened when two Russian Su-27 fighter jets flew up to the MQ-9 Reaper drone over international waters west of Crimea. “Several times before the collision, the Su-27s dumped fuel on and flew in front of the MQ-9 in a reckless, environmentally unsound, and unprofessional manner,” the US statement said. “This incident demonstrates a lack of competence in addition to being unsafe and unprofessional.”
