Why the emphasis on the missile? If there was no missile, the plane was still a legitimate military target.
Unlike the passenger train terrorist attack the day before.
To me, this is good news. I can definitely see how we are severely lacking in low cost disposable drone technologies. The American industrial complex would have us spending hundreds of thousands or millions of dollars on weapons that take a long time to build or stockpile. The ability to quickly adapt in the battle field is a necessity these days and low cost, rapid production of offensive and defensive drones or drone related technology has proven to be urgently needed.
