Simple. If it would be true all military aircrafts, ships and vehichles would have high-power lasers installed to blind enemy pilots and drivers and all guerrilla fighters would have pockets full of $3 chinese laser pointers to do the same. If it would be possible to disable a pilot for a many hours like this, no military aircraft would be ever able to approach any densely populated area. Dishonest horseshit.
Also from other comment: https://www.youtube.com/watch?v=S92XUsfI5ng How are they flying at all if this is true?
