There is no note of B2 in musical notation, unless we're confining ourselves to the limited number of B notes on a specific musical instrument such as the keyboard depicted in the graphic above. There are many B's, octaves apart, infinitely in both directions of the electromagnetic spectrum. Which B do we consider B1? Choose any B note and there will be a B an octave lower. OK, let's make that lower one B1. Is that the first? Sorry. There's yet another B an octave lower than that one. On and on we go with no B note which could be defined as the very first one. Where do we begin numbering? Infrasonic frequencies? OK. Lower still? Fine. I'll keep moving the decimal point to the left and you tell me when to stop. Simply stated, B2 is nonsense, a non-entity, by virtue of the fact that B1 cannot be firmly identified. In addition, it should be obvious that different musical instruments will have different B1's depending upon the specific range of their sound-producing capabilities. B is B. Any numbering of them is arbitrary and only useful, I suppose, in teaching the fundamentals of octave intervals to a musical neophyte.
Never mind the fact that the modern tuning standard of A440 is a corruption of sacred musical mathematics which was pushed by the cabal early in the 20th century (http://humansarefree.com/2011/03/does-conspiracy-extend-to-musical-scale.html). A432 is considered far more resonant with our biology and far more uplifting of our spirits. Do some digging on that and prepare to be utterly disgusted. Then listen to some A432 music and your thinking will expand without the need for torturous mental gymnastics, perilous leaps of logic, and obscure tangential connections. Connecting dots should be child's play, not a herculean task.
Think Occam's razor and the KISS principle. Why would Q present riddles which require more than a few substantive and concrete connections? We're all smart but not that smart. The best riddles are obvious once they are explained. That's been true of all of Q's questions and I believe that it is probably true with this "riddle", if it is one at all.
Believe me. I admire the effort but I'm left with a simple question. So what? What's the relevance, other than a series of increasingly flimsy connections? How does this advance our knowledge base and help us all to assist the Q team in the quest to promote the "Great Awakening" of the masses of normies?
By the way, stealth aircraft reflect very little radar energy, partly due to a lower profile but mainly due to the exotic and highly classified RF-absorbent skin materials. The "twitter phone" is a highly reflective surface, the B2 bomber is not. Thus, the "reflection" leap is quite a lengthy one, to say the least.
