I quite agree that the sniping should stop (although if it's merely directed against me that's fine, it doesn't bother me - it just annoys readers of the thread). However, when you use terms like "witch hunt" I think you're possibly overdoing it slightly.
To ask serious questions about TVOC is entirely within reason. Indeed, I can't think of a more suitable forum (if you'll pardon the pun)!
With reference to your comment bubble, I think you're referring to the tail cone which does indeed bulge. However this was a later "add-on" development of the basic airframe, when ECM equipment needed to be fitted. The original B1 (and B2) tail cone was simply tapered to a point.
