If you think about it, it's probably all about Mortal Oscillatory Rate (MOR) just like a Rife Machine uses, just more powerful. Find the MOR of steel, and you can break it's molecular bonds by frequency & vibration. Aluminum? That's just a different frequency. Titanium? That's another frequency...and so on.
Hard to fly a plane or a missile if it's aluminum is turning to dust.

I listened to a DOD retiree saying the towers were hit .. turning the debris mostly into dust ... They knew the amount of material that was taken away .. IT ALL DIDN'T ADD UP .. I cannot remember the method to the destruction ... it did involve RAYS .. .frequency ... and people could not realize what was taking place .. It was also said our military at this time is working on an instrument our troops can wear to alert them .. It is like when our medical staff while working in the hospital are required to wear a badge that will alert them .. they have reached a dangerous range of RADIATION POISONING .
