The battery in the video camera died right then. :)

The image distortion is actually expected and is acceptable.  With cockpit 
structure in place, it would mask that distortion band along the bottom.

The screen is actually covered in kraft paper - it's all we had on hand at 
the time.  It's badly wrinkled in places. :)

Note that collimated display systems are not really usable or meant for 
bubble canopy equipped airplanes.  It won't be used with the F-15, but 
we're looking at building both a single & dual seat cockpit that would 
work within the 8ft diameter of the next version of the display.

The box is not louvered - you're seeing the ribs that make up the toroidal 
shape that makes the screen.  The ribs are 1/8" thick and spaced 3 degrees 
apart. Like the mirror, its only a 60 degree wide test assembly.

Political correctness is a doctrine, fostered by a delusional, illogical
minority, and rabidly promoted by an unscrupulous mainstream media, which
holds forth the proposition that it is entirely possible to pick up a turd
by the clean end.
