Yeah, I think you’re right, but I don’t think it would be due to GG exhaust. Too much mass, and not enough thrust to produce a large enough roll moment in that fraction of a second (considering the size of the deflection). Maybe something in the way the guidance system senses LO (vibration, etc), or, like I said, signal spike during plug pull out. In that flight, it was bad enough they thought it might have to be terminated, but it was just a transient and all went well.
@hammeredinfire Most Atlases had a roll transient at liftoff - perhaps due to the turbine exhaust being directed to the side. Many Atlases show a vernier deflection at liftoff.
@chappychap probably because they were the first capable boosters. That's like saying that early cell phones/televisions/every other new technology sucks. Of course it sucks compared to more advanced tech. If it didn't we would all still have monochromatic television with rabbit ear antennas, briefcase-sized cell phones, and Nickelback's first album.
@ceredigio I think those are pad sirens they turn on before ignition in case some clod somehow finds himself on the pad at the wrong time he can make his presence known or run for cover.
You can tell it’s John Glen’s flight because the verniers momentarily swing to full deflection at liftoff, probably due to a ground fault from plugs not pulling out in the order they were supposed to.
@ceredigio I'm not really sure about this but that sound's because of those towers retracting at 0:12 to 0:13 (see them?) Like you said, the Titan 2 made a similar noise as well....... Uh-huh. It also had those towers that retract.
yeah loper, since this and the Redstone were basically created as nuclear missles and were meant to get to their locations in a hurry (usually somewhere in or near the Soviet union)they were pretty fast off the lines.
The Saturn 1-b and Saturn V were engineered to be slower so they astronauts would have less G force on them, of course when considering the weight of the Saturn V against its thrust its not exactly going to jump off the pad like a small Redstone.

Wow chappy maybe you should tell NASA how awful the Atlas is they only used it for 45 years,made 600 launches with them.

The Shuttle also takes off much faster than the Saturn

This in fact is John Glenn's launch in 'Friendship 7', Feb 20, 1962
Why does the Atlas make that high-pitched racket before it ignites? The Titan 2 made a similar noise as well

Much faster lift off then the mammoth Saturn V.
Must have kept the astronauts in their seats.
Thanks for uploading.
