A US Global Hawk drone flying with its identification systems turned off was shot down by Iran leaving a very expensive debris field in the Strait of Hormuz (archived). A high endurance, high altitude surveillance drone intended to replace the cold war era U-2's mission, each Global Hawk drone carried a 131.4 million USD manufactering cost which balloons to 222.7 million USD when program research and development costs are accounted for. With tensions between Iran and the USG rising, democratically elected US President Donald Trump tweeted in response to the incident that:
"Iran made a very big mistake!"
In light of defections trending in Iran's favor and the USG butthurt over losing a drone with identifying equipment off, an especially grave violation of international aviation norms in light of the 9/11 airplanes as rockets incident; who is really making the mistakes?
