"'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.'
'Our MQ-9 aircraft was conducting routine operations in international airspace when it was intercepted and hit by a Russian aircraft, resulting in a crash and complete loss of the MQ-9,' Gen James Hecker, the US Air Force commander for Europe and Africa, said. “In fact, this unsafe and unprofessional act by the Russians nearly caused both aircraft to crash.'"
LOLOL But it didn't; it caused your aircraft to crash and the Russian aircraft to be fine, hence perfect competence. Now if the Flanker went down, either with the drone or somehow without, that would be incompetent. Basically, when the US says, "unsafe, reckless, and/or unprofessional," it means it was skillfully executed and very effective at being bad for America.
