Submarine-launched missles take off vertically. I would suspect the same with silo-launched. Air launched, horizontally? Yes, they are steered during flight with constant course corrections. ICBM is probably the same as they are often fired from silos or even submarines. |

With ICBMs, I would think range maximization comes from the fuel load.
Once you have the world covered, there is no need to go any further.
Precision becomes more important.

The Minuteman III is a multi-stage missile with an in-flight computer called a missile guidance set (MGS or "can""...it's Byzantine technology). There can be course corrections in flight and I want to say it's based on celestial reference. In the post-boost phase (once the solid-fueled stages burn out and separate), a small liquid-fueled engine allows for some trajectory correction, too. Once that "bus"separates, the reentry vehicles (warheads) fall to the Earth, with a spin, via gravity.
Not the same as artillery exactly, but ballistic theory is obviously a big player (what the "b" in ICBM stands for).
As I said, though, I'm not really an expert on the flight mechanics. As a missileer, my job would be to turn keys if the President ordered it. Once "positive launch indications"/"missile away" notifications were received in the launch control center, all I'd have to worry about for that sortie is the "smoking hole" it left behind.

Speaking of missiles, I can shoot a 12" (not stretched) rubber band almost 40 feet. Launch angle is nominal, approximately 15 degrees due to low ceilings in the office. I once shot a court room deputy through his newspaper from about 20 feet.
So, I have that going for me.

Holy smokes. That's one heck of a long way from shooting off the stars (a much under appreciated art form) and measuring powder temperature, winds aloft, and earth's rotation during flight time. I'm an anachronism. |

So I can appropriately post in response to dshawn 's inquiry: Here is another Plan B for those looking to get out of the legal field: Starbucks Career Center |

I may need that if I keep spending so much time looking on here. I am not even in the running.

That would be Plans B, for you grammarians.

@spn Lifer
So, is it "rights of way" or "right of ways"? TIA.

@spn Lifer So, is it "rights of way" or "right of ways"? TIA. I would go with "rights-of-way. The rights would be the noun that is made plural. Similarly, the plural of spoonful would be spoonsful (although the spellchecker in my browser is suggesting that's incorrect by showing me a red squiggly line beneath it). Spoonfuls has become the preferred choice, and that is evidenced by the absence of a red squiggly line as I'm typing this. Maybe I have no idea what I'm talking about. |

Thank you, JudgeKnot! The ROW spelling is useful information for my current work. (But what if sthingysful is spelled sthingiesful? Nope, the red line still appears.)

Likewise, the plural of cul-de-sac is culs-de-sac, not cul-de-sacs as many would say. Hate to be a bore with an on-topic post, but for those with background in communications & communications law, an FCC GS15 slot is open to the general public! www.usajobs.gov/GetJob/ViewDetails/479001900Sacre bleu! |
