This is so great. I am so thankful that you did this.

Listening to the description of how the LM worked, a remarkable thing occurs to me. Not only is it unique for the time to have a throttleable engine, but BOTH the descent and ascent engines had to be throttleable, AND they were controlled from the same place.

[@dandavenport4565]

The x15 super sonic research plane used two different rocket systems. Both of them could be throttled up and down. This took place eight years or so before the first flight of the lunar module.

@@dandavenport4565 Must admit I didn't know that. How did they work? It wouldn't have been like the LM, where you use one, jettison it, then use the other. Did they work in parallel, or what?

[@dandavenport4565]

@@ronaldgarrison8478 I didn’t say that very clearly. During the first years of the X 15 flights, they used two sets of four rather small rocket engines, which I believe could be throttle. Later they develop one single rocket engine, with far more thrust that could be throttled via a controller in the cockpit.

@@dandavenport4565 Oh, OK. Thanks for the clarification. I would expect the Wikipedia page to include these details, but I haven't looked, so don't know.

Are you kidding? Circles? What a waste. 😮

Absolutely ridiculous...nonesensical Bs

[@cavsterxii2068]

Aww that's a shame you think that.

You can't even spell, "nonsensical."
Nobody can respect your comments.
