[16 lines quoting entire MBT-70 driver disorientation problem
 deleted. --CDR]

The B-17 had a similar problem.  On the prototypes for the first turret
armed versions (E, I think) they initially tried to use electrically 
controlled ball, top, and perhaps tail turrets, using a complicated
mirror system to aim the gun.  The gunners became disoriented, and could
not track targets, so it was resolved to place them in the turrets
as on the medium bombers.  When a chin turret was added (G model?)
it was controlled from within the nose section by either the bombardier or
the navigator.  The B-29 managed to lick these problems, all guns aside
from the tail gun were controled remotely.

	[OK, so how did the B-29 fix the problem and why couldn't
	 they use that for the MBT-70? --CDR]
