I got six inches of nice new snow on my deck. My deck is easy walking distance to Peabody slopes over at Cannon. So if I got six inches, Peabody slopes got six inches. Cannon summit might have gotten a bit more. Skiing ought to be really good this weekend.
This blog posts about aviation, automobiles, electronics, programming, politics and such other subjects as catch my interest. The blog is based in northern New Hampshire, USA

You can teach your child to read.
The Internet is full of stories of public school were NONE
of the children could read at grade level.
This is astounding and discouraging.
I went to public school many years ago, and things were not that bad,
then.
First thing you can try is to get your kid out of the
failing school and into a better one.
The Catholic Church runs many parochial schools, from kindergarten up
thru 12th grade that do an excellent job. My three children attended parochial school
even though we are not Catholic. Best
move we ever made.
Or you can teach the child yourself. If you graduated high school you are better
prepared for teaching than any education major out of college. Motivation is a key step. You need to read aloud to the child. When he/she sees that Dad or Mom reads, they
want to do it to. You need some good books, written for kids your kid’s
age. Weed out any books that go off into
politics, or critical race theory or sex, they merely bore young children. Dr Seuss is very good.
There are two ways to teach reading to children, phonics and the “whole word method”. Stick with teaching phonics, whole word is unteachable and does not work in many cases.
For phonics the child needs to know the names of each letter
of the alphabet and the sound each letter represents. The Alphabet Song from preschool works well
for this. And the child needs to
recognize upper and lower case letters and understand that the pronunciation
does not change because of case.
Now we can start phonics.
Start with simple short words like dog or cat. Have the child say the letters of the
word. With some repetition the child
will hear the letters and the word they form.
After some phonics work give the child a reward by reading something out
aloud.
After a while the child will be able to just look at the word and know its meaning, pronunciation, and some connotations and denotations that go with it. This is the beginning of “whole word” method. Keep up the phonics. New readers encounter a lot of words they have never seen before, but they can sound them out and get them with practice.

Hot Box.
Old railroading term for an axle running hot in its journal box. Trains have a lot of axles, four per car. In the old days, before 1955 or so, the axle bearings were friction bearings. The end of the steel axle rotated inside a solid brass bearing inside the journal box (square box with a tip up lid on each axle). The journal box was filled with cotton waste soaked in oil to keep the bearing cool. Trainmen used to walk up and down the train carrying huge oil cans and giving a good squirt of oil into every journal box that needed same.
Freight trains had cabooses, in which a couple of trainmen rode to keep an eye out for hot boxes. The cupola on top of the caboose was used to eyeball the train looking for hot boxes that might be starting to smoke.
When a hot box was
spotted the train was slowed, taken to a siding, and the hot box oiled to make
it happy. Trains did not proceed with
smoking hot boxes for fear that the hear might melt the end of the axle,
dropping the wheel assembly crosswise onto the track, and causing a serious
accident.
Roller bearings came into service in the 1960’s, and are
universal today. They are much less
prone to hotboxes than the traditional friction bearings.
There is video from that train wreck in Ohio
showing one of the car trucks not just hot, it was engulfed in flames. The train crew should have seen it. They failed to do so, and ran the train until
the axle did fail and wreck the entire train.
The TV newsies haven’t asked why the train crew failed to pull off onto a siding.

Shooting down “objects”
Of the four “object” shoot downs, two went into the water
and two went down above the Arctic Circle. The Navy is still trying to salvage the big
one shot down off South Carolina
in only 47 feet of water. I doubt they
will ever salvage the one shot down into Lake Huron. The winter weather around the two
Arctic Circle shoot downs is so bad we may never
find the wrecks.
Translation: If we
want to know more about these “objects” we gotta shoot them down over land,
places with reasonable weather. So far
from four shoot downs we know zip.
A piece on the Internet claims the Sidewinder missile that missed one shot cost $439,000, nearly half a million, for an air-to-air missile. Gold plate much? The first sidewinders came into service during the Korean War and only cost $10,000 apiece.

Gold plating everything runs up the cost of defense.
Gold plating is the tendency of our military services to require expensive and unneeded fancy equipment added to nearly everything they buy. For example, the WWII Jeep did the job. After the war we civilians could buy new Jeeps from the Jeep dealer for something like $3000. First thing they tried was the “airborne Jeep”, made as light as possible to make it easier to parachute it from cargo places. And it had the same swing rear axle from the GM Corvair that Ralph Nader condemned. The troops rolled a lot of airborne jeeps over, often killing them selves. And parachuting the “airborne jeep” would smash it up making it look like a beer can someone had stamped on. I remember walking by the Aerial Port where there was a long line of beat up jeeps. They had been used to practice parachuting them. The old WWII jeeps looked dirty and battered but they looked like they could be made to run again. The “airborne jeeps” were so bent out of shape that I don’t think they were good for parts, let alone getting them to run again.
And after the “airborne jeep” faded out of memory, the services decided they needed something a little bigger. They bought HumVees. A new HumVee cost $60,000. So expensive that only Arnold Schwarzenegger could afford one. A far cry from the $3000 for a WWII Jeep (Jeep CJ).
Then we come to USAF. I was maintenance officer in a squadron of F106 fighters. Basically a good fighter. Designed to shoot down Russian nuclear bombers coming at us over the North Pole. It was fast, Mach 2, so it could catch anything, good range, it could fly from Duluth Minnesota to Tyndall AFB at the southern most tip of Florida without air-to-air refueling, or making a fuel stop. It carried a big battery of missiles. The ones in my squadron were built in the late 1950s and kept flying into the 1980s.
One big piece of gold plate on the F106, the Tactical Situation Display (TSD). This was a 9-10 inch screen that was supposed to display your position, and the target’s position, like that groovy display in the Bond movie Gold Finger, the little display in the glove compartment that showed Bond’s car and Oddjob’s car at once. Trouble with the TSD was it was totally unreliable. Just the engine vibration from flying the F106 would break it. We couldn’t get replacement TSD’s, we couldn’t get parts to fix the broken TSD’s, and by the time I joined the squadron the boys had given up on the TSD. When it broke they just left it in the aircraft. What’s worse, the TSD didn’t do anything that needed doing. The F106 had very powerful radar in its nose that would show targets out to 200 miles. It had voice radio to the ground controllers who were more than happy to tell the pilot about the target’s position, course, speed, and altitude. Who needs a TSD with that kind of support?
Some things we could do. All these gold plate boondoggles are made in Pentagon meetings. Mostly procurement paper pushers attend them. We ought to require that specifications for weapons systems be reviewed and if necessary vetoed by operators, pilots, aircraft maintenance mechanics, submariners, navy officers, and others who actually know something.
W should insist that the armed forces buy stuff off the civilian market and not require (and get soaked for) a custom military only design.

The US Army is planning on a new rifle cartridge. And new rifles to shoot the new cartridge.
The modern rifle appeared after the US Civil War, say 1870 or so. These were Winchester and Marlin lever actions, early bolt actions, and other competitors. They were mostly chambered for a .30 caliber center fire cartridge with enough power to take American game, such as elk, deer, buffalo, bear, and wild hog. This rifle cartridge served well from the Spanish American war up thru WWII. Korea and Viet Nam.
During WWII the troops fell in love with full automatic weapons, the Thompson submachine gun and the M3 “grease gun”. From the soldier’s point of view, the ability to point the weapon and hose down an entire enemy unit with one quick “BRAP” could be life, should they encounter a strong enemy unit in combat. The American WWII sub machine guns fired pistol ammunition, the .45 caliber round used in the Army .45 automatic pistol. The pistol run lacked the power of rifle rounds, but the recoil was light enough to permit full automatic fire from a 7-9 pound shoulder weapon. The regular rifle rounds kicked so hard that they just drove the rifle up until it pointed at the sky.
After WWII the Army adopted the full automatic M16 rifle. To get the recoil down enough to make the gun usable in automatic fire, the power of the M16 round (5.56 mm) was reduced quite a bit. The real riflemen in the army still liked the WWII 30 caliber round, it reached out further, it could penetrate more body armor and it made a sniper more effective than the 5.56mm round from the M16.
So after decades of grousing about the lack of power in the standard 5.56 mm round, the Army has announced it wants a 6.8 mm round (.270 a civilian gun shop would call it) The army claims that the small increase in bullet diameter will give a round with ballistics nearly as good as the antique .30 caliber rounds and light enough recoil to allow fully automatic fire from a 7-9 pound rifle.
Needless to say, adoption of the new recoil will require the army to replace all the M16 rifles with whatever will fire the 6.8mm round. And all the machine guns too. This could become very expensive.

What parents need to do about fentanyl. Before it kills their children.
Six out of ten sample pills bought from street drug dealers contain enough fentanyl to kill. Your children need to know this. The MSM doesn’t talk about it, so unless you, the parent, pass the word to your children, they won’t know. Taking just one pill bought from a street drug dealer has a 60% chance to killing the child, right then and there.
The few times the MSM mention this tragedy they call it “a drug overdose”, implying that the victim took too much of the drug. Better is to call it deliberate poisoning, because the drug dealer sold the child a pill with a lethal dose of fentanyl in it and when the child swallowed that one pill, it killed him.
If the children just have to get high, they should stick to alcohol or weed. Neither of them is good for the kids, but they won’t kill them as quickly as fentanyl laced pills from the street will. And, if the children just have to get high, they ought to do it in their rooms (dorm rooms) and not be out driving. Just one can of beer can discombobulate a beginning driver and cause a fatal car accident.
