"Initial indications from an initially miniscule research set suggests that drone strikes do not hurt aircraft. As more collisions happen, I'm quite sure that eventually one will go down an engine. That will be more indicative of whether there is actually a problem " .
Well on that basis, we might as well stop educating people about the dangers of FOD then.....after all, what could possibly happen to the engine when one ingests solid matter.
I am sure you have seen the results of bird strikes on both the airframe / engine and the damage that results..one of my most memorable being a seagull vs Harrier.....went in through the nose and then through the front px B/H resulting in a right rudder restriction....so a drone I would suggest is equally capable of inflicting serious damage.
