Donald Trump Thinks that the F-35 is Invisible to the Naked Eye...

[Fireball]

I can personally attest to seeing a B-2 wing-over in flight and seemingly disappear from sight. I can also attest to the fact that I used to be able to hit targets with great accuracy at the gun range using iron sights (cover 5 shots with a dime), and now need to use a scope. There may be a certain amount of credence to the lack of optical visibility to the F-35, based on another 30 years or so of development on low observable technology. But "invisible" won't be in the "real" lexicon of low observable tech for awhile yet, as far as I know. I haven't worked in that industry in over 25 years. It may well be that the chump was mixing up the fact that the F-22 (which I did work on) can attack enemy aircraft before they (F-22s) can be seen, even on RADAR. An enemy won't know they are under attack from a missile until it is WAY too late. Of course, in the chump's case, possibly 1 word in 10 successfully passes his filter correctly.
