A HB complained that the screens in the Houston control room were too big. He claimed there were no TV tubes nor TV projectors so big at that time, so that must have been film, not video.
Weird claim. But what were the big screens at Houston? I suppose they were video projectors.
Thanks.

hi Jairo, tell the HB he'd be wise to research en.wikipedia.org/wiki/EidophorConsidering the device has been around since 1939, there isn't really any excuse for his stupidity. Good luck getting him to admit he has no idea what he's talking about.

Thank you! I think I would waste days looking for this.

Wow! Awesome, Dwight. I had wondered about that.

You guys are welcome. I have some documents regarding the projectors, but I need to locate them...
In the Apollo 13 press kit (IIRC) there is a MOCR floorplan which shows how the projectors were set up.

Wow, what a fascinating piece of broadcast history. I had always been curious about this personally, in a "Now , how did they do that?" sense.

There's an interesting comment in the Wikipedia article - some of these Eidophor screens implemented sequential color; I guess that means Mission Control could display color without relying on the NTSC scan converter that produced the feed for the broadcast networks.

Charlie Duke mentioned it by name when the Apollo 11 CSM was bringing its crew back to Earth -- then screwed up two sentences later.

See, when things like that come up, I think, "Well, there's probably something I don't know." Instead of assuming Apollo was hoaxed because they didn't fit into what I did know. Then again, some HBs know everything, so of course Apollo must have been hoaxed given its failure to fit into what they know.

Then again, some HBs know everything... Indeed. Little do they know about the little I know about the little they know. If they only knew a little about the little I know, they'd know a little. But then again, if they only knew a little about the little I know, and I knew they know only a little about the little I know, then they also would only know a little about the little I know about the little they know.

It just goes to show how fiendishly creative the hoaxers were, that they invented a technology to support it 30 years before the hoax!

Fascinating. They sound like they would have been hard to repair if they stopped working.

I know you're being partly facetious, but I think this really is what being a HB is all about. Most people welcome information they didn't already know. That's how you learn. That's how science progresses. But HBs, for some reason, find new information upsetting and threatening, so they look for ways to blunt or counteract it.

I'm not sure "facetious" is the word. I mean, obviously, I don't believe they really do know everything, but I think I was making exactly the point you just did.
