Nah.. I think they screwed up. BUT, they did offer other
streams. If I remember correctly one of them was an
"interactive" thing that DID have the gauges on the lower part
of the screen, and the top was some kind of visualization of the
descent. They sometimes showed that one for a few seconds
during the stream that I was watching. But most of the time it
was just a view of the engineers sitting behind their consoles -
waiting.

True enough. They probably had to work within certain initial
guidelines and cut back with things (lighter material, less
cables, etc) until they were within spec.

Yes.. I forgot about that.

I saw the one pic showing the sky crane cables. That was a good
quality pic. I wonder what kind of bandwidth they have for
tranmitting video back to earth.
I was really impressed with the TRNS (terrain relative
navigation solution) radar, to scope out and select the best
landing spot and only having a few seconds to do that, and then
having the jetpack navigate to that spot.
