I have no clue what the intent for this design is/was, but personally (having experience as a mechanic/welder/fabricator), I wouldn't fly in that thing at all (especially if a computer is all that keeps it from mechanical self-destruction).True. That's what struck me as most interesting about this aircraft--the fact that the tails weren't connected. That has the potential to put huge twisting loads on the central wing section, so there must be a combination of computer active control of the empennages and some remarkable materials in the central wing. My only guess as to a reason for such a design is to leave more clear space in the middle for the payload spacecraft than a connected tail would provide.
I just hope it survives the test flights without killing a bunch of folks.
Maybe (hopefully!) I'm wrong.
