Military pilots and ground crews showing high rates of cancer, Pentagon study reveals

​

Navy A-6 Intruder pilot Jim Seaman died of cancer at age 61. He is one of a group of pilots who were diagnosed with cancer, the Associated Press reported. His widow Betty Seaman has been part of a large group of aviators and surviving spouses who have lobbied Congress and the Pentagon for years to look into the number of cancers aviators and ground crew face.

Wow that's strange. Wonder what is causing that, or is it just a huge coincidence.

A good chance that it's largely coincidence, but that's certainly not for certain.

Anyone that wants to assert that this somehow proves that air/ground crew service causes any of the types of cancer that had an increase, better be prepared to explain how that same service somehow prevents lung, bladder, colon, and any other cancers that saw a decrease.

 

Wrong way impaired driver.

I wonder what it was that exploded. I was in about the right position to be a fuel tank, but it clearly wasn't. First, that would have blown flaming fuel all over the place that would have kept burning, but also it's clear later in the video that the fuel tank is intact. There are a number of canisters of things on a truck, so I imagine that one of them got hot enough to burst. Fortunately, it wasn't very energetic and the firefighters weren't too close to it when it let go. What's a bit surprising is that they even got as close as they were when it went. They know there are plenty of things that can go boom in any vehicle fire, especially one that is as fully engulfed as that one. My first thought was that he was doing an assessment to see if anyone was inside, but it doesn't look like it. It looks like they were just laying out the hose getting ready to put water on it, something that should have been done from further back -- and that the video shows WAS done from further back after the boom.

 

Hello again,

Talking about "being a passenger" i am glad i am not a passenger on an E Bike (i dont own one or rent one). In New York they had a fire that burnt the whole place down and the FD could not put it out. The cause was a faulty Li-ion battery that powers the device. I imagine it was large like 7Ahr or something like that.
They found out that there are either fake or just plain defective batteries being sold as safe and that is causes all kinds of problems. They said they have to make a law to have the bikes certified, or maybe it was the batteries that have to be certifies.

I'll tell ya i don't worry about too much these days but when i see what an Li-ion battery can do it worries me a lot. The fires are too hard to put out so it can cause a lot of damage. I have two fire blankets and i intend to get a certified battery box that can contain Li-on cells that start on fire. I dont really have that many but i do have some and any one of them could cause a problem.

From what i have read now, the LiFePO4 batteries are much safer because their temperature does not rise as fast when there is a problem. They are also very very light weight maybe 1/3 or even 1/4 the weight of a lead acid battery of the same capacity.

Anyone know of a fire extinguisher that will put out an Li-ion fire?

 

Unless you store those batteries (including any equipment in which they are installed) in the box, the box isn't going to do you much good. Once they start on fire, you aren't going to be moving them.

Despite the name, they are NOT combustible metal fires (there's no metallic lithium in them). They are considered a flammable liquid and the proper extinguisher to use is a Class B extinguisher.

The trick is that you have to get everything cooled to below the auto-ignition temperature of about 500°C, otherwise they will re-ignite spontaneously. That's what makes them so hard to put out. CO2 extinguishers have a significant cooling effect, so that's good, but you have to be pretty close to use them -- closer than I'd like to be.

Hello there,

Well thanks for the info I'll be looking into the Class B extinguishers next.
My main goal of course is to be able to handle anything that goes wrong in a short enough time to prevent big damage.

Yes, i intend to store them in the box. They are for backup use not immediate use, and luckily I don't have a lot of them right now.
I have one larger LiFeOP4 but I read they are not as bad.

As to the lithium metal, there is more than one kind of Li-ion. I believe the kind you are talking about are the most common. I have mostly those but another type I have, I have to be a little more careful with. They are the higher current type.

Lucky a lot of these have a protection circuit in them, but some still don't.

Ok, off to read more about the Class B extinguishers.

 

 

 

Highly technical, but very interesting:

FAA Issues AD For 737 MAX Loose Fastener Checks

​

Investigations by Boeing revealed that some fasteners for the exhaust ducts were installed at the factory with inadequate torque using a prohibited yoke-style torque wrench adapter.
The FAA says the use of this adapter will “produce a significant under-torque of the installed fasteners. Inadequately torqued fasteners may loosen over time due to engine vibration, eventually causing the fastener to drop into the inlet inner barrel.”

 

Hardtop to instant convertible.

Absurd 200-Foot ‘Railway’ Demolished After Court Closes Shipping Loophole

Built around 2012, the Bayside Canadian Railway was operated by a subsidiary of American Seafoods to circumvent the Merchant Marine Act of 1920, known as the Jones Act. The law requires shipping between American ports to be handled by American-built, American-flagged vessels, with an exemption for goods moved by rail in Canada. The Bayside Canadian Railway used this loophole to push semi-trucks containing foreign-shipped seafood 100 feet down a short railway and back, ostensibly fulfilling the Jones Act's rail shipping clause.

 

Engineers have been trying to build an economically justifiable vehicle like this one for decades. I wonder if it will finally catch on.

It's not big enough. A single rogue wave will take it out.

Does anyone know what they are referring to when they talk about a "yoke-style torque wrench adaptor"? I've never heard of such a thing and I couldn't find anything quickly via Google. The only thing that comes to mind would be using a crowfoot extension on a torque wrench. I don't think that's what they are talking about, although few A&P mechanics that I've run across can actually do the calculations to use those correctly.

Same thought here, more or less... but maybe it could best be used in places such as the Great Lakes?

I think that would be the U shaped part which also has a handle at the bottom of the U and at the other end of the 'handle' a square hole for a ratchet drive or maybe a regular torque wrench. There would be an adapter that fits into the U part that fits the shaft of whatever is being turned and measured.
The handle and U part would look like an open end wrench without any hex, just an open U shape.
The adapter may have a dial indicator included or that may be the only thing used to do the measurement.
