They ain't including return envelopes in bills
Four of my suppliers did not include a return envelope in their bill this month. I had to hand scribe a return envelope for each of them. PITA. A new cost cutting measure? I'm not talking about a stamped return envelope, just a window envelope that lets the company's billing address on the payment slip show thru.

Middle school was getting bad back then
I wrote this for Youngest Son back when he was doing middle school some ten years ago. I wonder if things in school are still this bad.
1. Never say the word "gun" (or shoot or fire or kill or bang-bang or...)
2. Never take any thing that looks like, sounds like, or might be accused of being, a gun to school. Same goes for any kind of knife, even a butter knife. Don't bite your food into gun shapes. Don't point a finger, or anything else at anyone. No toy soldiers, no Lego guns, no books about guns or with illustrations of guns, or people carrying guns (cowboy stories, Johnnie Tremain, Last of the Mohigans, anything like that).
3. Never say anything angry about anyone or anything. If something or someone angers you don't say anything about it. Hold it inside yourself until you get home. Never threaten anything.
4. No touching, no hitting, no hugging. Keep your distance.
5. They are always watching you and listening to you. Especially on the bus, at recess and on the Internet.
Forget any of these rules and they will throw you out of school, for good.
School was easier to survive when I was a kid.

The Battle of Britain
Decisive WWII action.
Had the British lost, Hitler would have invaded Britain
and that would have changed everything, for the worse. In the spring of 1940 Hitler looked
invincible. He had conquered and
occupied Poland, Denmark, Norway, Belgium, The Netherlands, France (a great
power) and driven the British (the other great power) into the sea at Dunkirk. Although the British had managed to rescue
most of their soldiers, they abandoned all their tanks, trucks, artillery,
tents, rations, and ammunition. Only a few troops retained their rifles. Had Hitler been able to put a few divisions
ashore in England
in the summer of 1940, it would have been all over for the Brits.
Only the Royal Navy
stood in the way. Had the Germans set
out for England
in their fleet of Rhine River
barges, the Brits would have steamed up along side in destroyers and blown the
Germans out of the water. The Brits had
better than 100 destroyers backed up by 30 odd cruisers and a dozen
battleships. They had sunk Graf Spee and Bismarck. The actions off Norway
had wiped out most of the German destroyers.
Those river barges would have been on their own crossing the
channel.
The German
Luftwaffe might have been able to drive the Royal Navy away and safe guard the
crossing. For this to work, the
Luftwaffe had to establish air superiority.
You cannot be attacking RN destroyers with Spitfires on your tail. This means shooting down RAF fighters in the
air and bombing RAF bases out of operation.
The Brits knew what
was coming. They had invented and
installed the first modern air defense system.
We were still using the idea in USAF in the 1960s. It consisted of ground radar, linked by
telephone to “sector stations” which scrambled the fighters and gave them
vectors and altitudes to fly for interception.
Without the radar Luftwaffe strikes would have surprised the
RAF on the ground unless the RAF flew reconnaissance sorties to spot the
Germans at a distance. The number of
recon sorties would have huge. A fighter
unit can only put up so many sorties a day.
To waste all those sorties just flying around looking for the enemy
would have meant the end for the British.
With the radar, the British fighters could stay on their fields, all
fueled and armed, ready to scramble, and count on intercepting the Germans on
pretty much every sortie. No sorties
wasted flying recon.
Had the Germans
figured things out, they could have bombed the radar stations. There were easy to find, being right on the
coast and having 300 foot high antennas marking their positions. And they could have bombed out the sector
stations by homing in on their radio transmissions. But, the Germans never figured out what was
going on and let the radars and the sector stations operate undisturbed. They counted on shooting down the Hurricanes
and Spitfires in the air, and bombing their fields. This didn’t work out because the British
planes and pilots were as good as the Luftwaffe planes and pilots, and the
British cranked up their aircraft factories and were building more planes than
the Germans were shooting down.
Why do we care? England
was a Great Power; she had 50 odd million population. Not too shabby even compared to our 100 odd
million back then. And England
could count on solid support from Canada,
Australia, New
Zealand, South
Africa, and India. India
put up many of the troops that beat Rommel in North Africa,
and later beat the Japanese at Imphal and drove them out of Burma. And, England
was the base for the air war on Germany
and for launching D-Day. Many of the
craft that landed in Normandy
were open landing craft. They could
cross the Channel in good weather but they would never survive crossing the North
Atlantic even in summer. In
short England
was key strategic terrain. Had the
Germans taken it in 1940 it is difficult to imagine how we would ever have been
able to beat Hitler.

We need to get the country back to work.
We need to get the country back to work. Every day we all consume food, fuel,
clothing, shelter and any one of a zillion different necessities of life. We are running out of stuff. We have to get back to work and grow,
manufacture, mine, frack, transport raw materials to factories, and transport finished
goods to stores. The whole country has
been out of work for eight weeks now. We
are running out of stuff. You can see it
when you go grocery shopping. Empty
shelves, missing product, lack of toilet paper, paper towels, whole milk, beef,
pork, and chicken at the butcher’s counter.
And most of us need
our paychecks. And business needs
workers. The governor allowed hair
salons and barber shops to open this week in New
Hampshire. I
made an appointment with Mane St Styles to get my hair cut. The
proprietor greeted me at the door, gave me a new mask to replace the
daughter-in-law made one I was wearing, took my temperature with one of those
high tech IR gadgets, and greeted me warmly.
All the staff were overjoyed to back to work. And it did feel good to get my hair off my
neck after two months.
Naturally as soon
as we do get back to work, people are going to catch COVID-19. Staying at home we are fairly safe. Getting out into the world exposes us to the
virus and some of us will catch it. Some
of us will die from it. And the medics
and the media will cry that we are killing people. Until we have a vaccine, and that is a year
away according to the TV, there is some risk involved. But that risk is the same tomorrow, next
week, next month, until we have a vaccine.
Can we keep the country shut down for a year waiting on a vaccine? I don’t think so. I am in the high risk group. But I will risk it just to eat at a
restaurant. I am tired of eating my own
cooking.
And, to get the
country back to work we need to protect our businesses from COVID-19
lawsuits. We cannot allow lawyers to sue
every business in sight every time someone comes down with COVID-19. People come down with COVID-19 because the
Chinese released the virus into the world.
If we give the lawyers their head, they will sue all our small
businesses clean out of business. Small
businesses don’t have lawyers on staff, they cannot afford lawyers, and just
the threat of unending lawsuits will kill them all.
By all accounts if
you are under 50 and in decent health, your odds are pretty good; say 0.1%
chance of dying. If you are over 70
(like me) and your health is not so good, your odds are a lot worse, say 10%
chance of dying. We should let people
make their own choices; we should not force people in fear of their lives to go
back to work. Likewise we should not
prevent people who want to get back to work from doing so.
Canned Catfood. Pate vs Shreds & Glop
I prefer pate. It is less messy to handle. Cat prefers shreds & glop. How can I tell? She doesn't eat much pate, but she will have all the shreds and glop eaten within the hour.

Barrows
I was watching a U-tube lecture on European archeology. They excavated a huge barrow in England. Built back in prehistoric times, before writing, all we know about then comes from archeology. It was a big structure, half underground, half above ground. These things are often described as graves. On this barrow, they excavated and found the bones of forty individuals. Forty? Not many for a barrow that big. The place was big enough to hold a 1000 graves. Especially when you think how difficult it must have been to build such a place in the stone age. Few workers, a poor hunter gatherer economy, no metal tools, not even shovels. It must have required powerful motivations to build those barrows.
Barrows are traditional described as grave sites. That U-Tube lecture makes me think that the barrows served other purposes. Tribal gathering places, sacred places where shamans asked the god for good weather, good hunting and good luck. Places where seers predicted the future. We cannot know at this remove in time. I.m thinking those few graves were the graves of a few exceptional individuals, priests, kings, shamans, mighty warriors, buried in the barrow to bring good luck, bring a friendly spirit, and make a sacred place more sacred. We still do this. Look at Westminster where the British bury their kings and scientists and soldiers.

Boeing's Number 1 Problem.
Best selling 737 Max has been grounded for more than a year. This is the brand new airliner that suffered
two fatal crashes within a few months of each other. The autopilot in both crashes failed, seized
control of the plane and dove it into the ground, killing all on board. After a year, the cause of the autopilot
failure is known, fixes have been made, but the aircraft (and Boeing’s very
survival) are still grounded. The 737
MAX is Boeing’s bread and butter aircraft.
It’s the single aisle jetliner that does most of the flying. They were
cranking out 57 a month ($100 mil apiece).
Production of all of Boeing’s other aircraft was only 20 per month.
FAA is still
paralyzed with fear of another 737 MAX crash which would reflect badly upon
them, and so they are slow walking all the paperwork. The Corona
virus epidemic has caused meetings to be replaced by teleconferences slowing
matters still more. Much more of this,
and Boeing will have to declare bankruptcy.
