[@richclips]

Thank you for posting this, I found it fascinating, really lovely presentation by some great people, thank you :)

[@Ramblin_DMC]

Great presentation! Thank you for recording and sharing!

My Dad worked on SAGE 1961-1966

[@blip1]

One of these blockhouses that he is talking about is still standing on the old Richard's Gebaur airforce base about 30 minutes away from me

[@uploadJ]

There is one in the Ft. Custer business park near Battle Creek too.

I have a number of the special tubes used in Sage as well as the vallley and walman book Valley the man that pushed the Sage even though the semi conductor was a better choose in the this case. the tube make very fine audio amps . Sound rather enjoyable.

[@uploadJ]

6SN7 tubes?

[@bcwingit]

Hancock Airforce Base still has the Direction and Combat blockhouses located in Syracuse NY.

[@patmoore9474]

I was stationed at Hancock Field. I worked on the Q7. I was there when it was shut down and help tear it out. Kind of sad actually.

[@thetreblerebel]

Humble and expensive beginnings of integrated ground control radar. Defense has always be the catalyst for innovation

[@thetreblerebel]

I imagine the "blue rooms" he was talking about was the ambient lighting not the glow of the screen, which I'm sure was in a green or yellowish color. The color blue was a mood enhancing, dont want stressed or agitated radar observers running a possible nuclear interception.

[@thetreblerebel]

The idea is still used in war rooms aboard subs and navy ships. And other possible tense environments in command and control

[@michaelcox436]

COBOL compool? I'm not aware of any such thing, can anyone add to this?

[@johnhopkins6260]

still remember 485L... (moved on to 407L - tactical)

[@thefajitas9795]

very cool!!

[@LTJR.]

A buddy told me that the cameras that were sent around the world to map it by balloon were controlled, well actually the servos in the cameras were controlled by Amplifiers and here is where I am a little shaky in the memory but it was either that the parts that comprised them later became the Macintosh tube amps, or That the Macintosh amplifiers were army surplus something like that but the more interesting thing that he told me was that they would do 100,000 K I guess necessary to physically move mechanical servos that far up in the sky? Anyone also hear that or something like?

[@youreale]

wow, love it

[@skiracerxray]

Operation Sky Shield Brits got through with jamming. Very interesting discussion

[@billpugh58]

We didn’t fly intercontinental distances though, the Vulcans flew off the coast and turned around and flew in at low altitudes impossible for Soviet aircraft of the time.

[@RCAvhstape]

14:00 briefing by Jim Carrey.

[@jtk8562]

yeah right thats not jim carrey wow so dumb

[@thetreblerebel]

A little on edge eh?

[@thetreblerebel]

No shit it's not Jim Carey. The guy is obviously a little nervous in his early 90s jacket

[@kasel1979krettnach]

i am bad with faces, they look like the same person to me

[@thetreblerebel]

All this, and it probably wouldn't have worked...that's early radar tech for ya..

[@uploadJ]

Okay Dunning-Kruger ...

[@freemanz4051]

Obviously not SOUND TECHs ffs!

[@ewaf88]

Oh those naughty Russians.However their 'aggression' in the 50's paved the way for rapid computer development.

[@billryland6199]

The F-100s shot down US B-47s.

[@mgabrysSF]

Hint microphones work best near your mouth - not across the room.

[@billpugh58]

21:37 he makes fun of dedicated patriots. What a Trumpist!

[@markskilbeck]

Yeah, that guy's totally not out of his mind on coke.

[@blip1]

mark skilbeck what?

[@ProximusRegent]

mark skilbeck he did seem jacked up, too much coffee or other stims.

[@thetreblerebel]

Glad you said it...I was totally thinking he was jumping high as hell

[@Jenalgo]
