Your theory doesn’t make sense..
So the “faulty steel” just now started to become a problem in the past week?
We would see downed military vehicles sporadically over a long period of time if this was due just to faulty steel.
Remember Q said the navy crashes were linked to aircraft.
It is much more likely there is a weapon used against electronics…think take over of plane or any electronic vehicle.
People need to learn who our enemy really is. Expand your thinking.
