"The pain was... I can’t explain the pain except to say if you’ve ever put your finger in a light socket as a kid, multiply that feeling by a gazillion throughout your entire body."

“And I saw a white light surrounding my body—it was like I was in a bubble. Everything was slow motion. I felt like I was in a bubble for ever."

From "What It's Like to Be Struck by Lightning/There’s a good chance you’ll survive. But the effects can be lasting."

MisterBuddwing म्हणाले...: As a kid, I got the idea that if you're in imminent danger of being struck by lightning, that you should flatten yourself against the ground. But later I heard that lying flat is one of the worst things you can do, because if lightning hits the ground, you can get fried pretty good. The new advice (as mentioned in this article) is to hunch down into a ball-like shape with only your feet touching the ground.

And whatever became of that advice that, in an electrical storm, the inside of a car is a safe place to be, since it's not grounded (because of the tires)? Do they not preach that bit of wisdom anymore?; २५/५/१७, ६:४९ PM

I have read many stories though, where cars have been struck by lightning.; २५/५/१७, ७:०४ PM
Owen म्हणाले...: I thought being inside a car was better because it would tend to act as a Faraday Cage and let the charge travel "over" you rather than through you. But lightning is weird. I once heard of a woman standing on a beach by a mountain lake; lightning struck the *far side of the lake* and traveled across the surface, through the wet beach sand, and through her. Killed her.; २५/५/१७, ७:०६ PM
Luke Lea म्हणाले...: When I fell off a cliff and broke my neck the pain was like an electric current running through my spine. Subjectively it had the volume of the Mississippi River and was going ten thousand miles an hour! I felt like a thread in a wind tunnel. I was slack-jaw awed by the magnitude of it, so beyond anything I could imagine. lt was a little bit like looking into the cosmos on a starry night.; २५/५/१७, ७:११ PM

The Faraday Cage effect is why a car is safe in a lightning strike. Stay in the car.; २५/५/१७, ७:१६ PM

traditionalguy म्हणाले...: What Do Women Want is a well acted comedy about a sneaky arrogant ad agency guy who gets a new talent, via lightening strike, to hear what women are thinking. He first uses it to use women like he always did, but then he falls in love with Helen Hunt's mind and romantic things happen...very much a chick flick but well done, especially the ones with his relationship with a teen daughter.

Oh...never mind.; २५/५/१७, ७:२६ PM

Browndog म्हणाले...: Not sure what it's like to be struck by lightening, or being electrocuted, but I do know what it's like to have your body's electrical system short circuit.

Twice. Once a heat stroke, once pneumonia.

Excruciating pain. The eyes see things that don't exist. The body feels things that don't exist. Time and space, a puzzle. Once out of the woods, it takes months to get your bearings. Flashes are constant.; २५/५/१७, ७:२६ PM
YoungHegelian म्हणाले...: In an email, Tushemereirwe described how the lightning protection that some schools do install can create a false sense of security. A rod may be installed on the roofline of one school building. But it’s not grounded.

There is absolutely no excuse for that sort of stupidity & incompetence. How difficult is it to stake a wire from the pole to the ground, for God's sake?; २५/५/१७, ७:३७ PM
rhhardin म्हणाले...: There's the European school and the American school on lightning rods.

The European theory is that a lightning rod bleeds off charge slowly so that lightning doesn't strike at all. The natives are up on their roofs sharpening the point on the lightning rod to keep it effective.

The American school wants the lightning rod hit and relies attracting and conducting to ground.

The contrast can be shown (at least in the winter when it's dry) by scuffing your feet on the carpet and touching a metal object with a key or coin (American effect - big spark), or with the point of a pin (tiny hiss, European effect).; २५/५/१७, ८:०४ PM
rhhardin म्हणाले...: Inside of a car is good. You can't get a spark inside unless there's a big voltage difference inside the car, and conduction through the frame keeps the voltage differences between roof and floor low. (explanation of the faraday cage); २५/५/१७, ८:०७ PM
rhhardin म्हणाले...: If you have a high impedance AC voltmeter (which most are these days of digital meters), set it on low voltage AC and stick the probes into the dirt an armlength apart. You'll notice about a half volt, which is just stray voltage from all the AC lines around.

If lightning strikes the ground, that difference rises to millions of volts, so standing in more than one spot on the ground is not a good idea.; २५/५/१७, ८:०९ PM
rhhardin म्हणाले...: The voltage differences in the ground is why if you ground a system, it should all be grounded to exactly one place, not two.

Otherwise you bring voltage differences into the system.; २५/५/१७, ८:१३ PM

Marvel has not fully penetrated the Nerd-O-Sphere.; २५/५/१७, ८:२० PM
rhhardin म्हणाले...: It's an open question, in a lightning storm, if you're riding your bike home, whether you should ride on the side of the road near the power lines, or the side of the road without the power lines.

If the line inductance is low, the powerline side would be best; if it's not (so a huge voltage drop can happen within the line when it's hit) then the other side would be best.

The power lines are either a shield or an attractor.; २५/५/१७, ८:२५ PM
John henry म्हणाले...: I got zapped real good when I was looking inside a control cabinet and bumped my head into an exposed 110volt cable. Luckily I was not grounded very well.

It took a week or so before I felt right again. It was not physical. I just felt really goofy all the time. As if I had drunk too much Nyquil.

Michael K म्हणाले...: "When I fell off a cliff and broke my neck..."

\When I was working in an ER during my residency, a guy came in who had driven his car off a cliff in Malibu. He climbed up the cliff and walked to the Malibu sheriff's station. They told him they could not help him. Somehow he got to our ER in Burbank (St Joseph's)

Complained of neck pain. I took x-rays of his neck. He had a C-2 fracture.

Amazing. No paralysis.; २५/५/१७, ८:२६ PM
rhhardin म्हणाले...: Curiously, though I worked with hundreds of volts as a kid, I never got zapped.

I think the 807 (or 1625) tube worked at 600v.

But I knew about large filter capacitors and had a hefty grounding stick.; २५/५/१७, ८:३१ PM
Richard म्हणाले...: Here is an article that explains how a cloud to ground lightning strike works.

https://www.ec.gc.ca/foudre-lightning/default.asp?lang=En&n=9353715C-1

Basically you have a channel of negative changes from the cloud called a stepped leader and at the same time currents of positive charges moving upward from the ground called streamers or upward leaders. The two streams meet approximately 30-100 meters above the ground. At this point a negative current begins to flow to the ground which completes the circuit. This is followed by a return stroke from the ground to the sky which is the main flow of current. If you are in an automobile, the insulation of the tires will prevent the car from being a source of the upward leader.; २५/५/१७, ८:३४ PM
rhhardin म्हणाले...: the insulation of the tires will prevent the car from being a source of the upward leader

There's no insulation in the tires when they're wet, and it wouldn't matter anyway. Another eight inches is nothing.

If you get hit by lightning, you may not notice. There's no thunder, which is a broadside effect, not an end-on effect. Just sort of a pfft.

I've been hit in a DC8 and a DC9, and the house has been hit, blowing off some shingles across the yard, but no particular noise in any case.

Trhunder rolls, incidentally, because the noise comes from all parts of the lighting bolt, and some of it is much further away than the closest part. The bang takes a spread of time to reach you.; २५/५/१७, ८:४० PM
Bleach Drinkers Curing Coronavirus Together म्हणाले...: How can anyone be stupid enough to still get hit by lightning these days? Except, of course, by being a climate denier.; २५/५/१७, ८:४४ PM
320Busdriver म्हणाले...: I was maybe 100 yds away from a gentleman who suffered a direct hit as he watched his child play in the surf on Daytona Beach. Initially I thought a car had exploded. It was still morning with bright sun and blue skies. The scattered airmass thunderstorms were just beginning to form some 20 miles inland, but there was not a hint of danger where we were. It took a few minutes to determine what had happened. The result was final.; २५/५/१७, ८:४७ PM
George M. Spencer म्हणाले...: When Benjamin Franklin invented the lightning rod, many of his potential customers refused to buy one for their homes...because, of course, they though it was God's will that lightning strike their homes, destroying them.; २५/५/१७, ८:५० PM
rhhardin म्हणाले...: Thunder has an irregular loudness when it's rolling, too, because temperature differences in pieces of air bend the sound rays; for some paths they're focused on you and for other paths they're defocused, depending on where in the bolt the sound comes from.; २५/५/१७, ८:५१ PM
320Busdriver म्हणाले...: The times I have been hit flying an aircraft there has been a loud crack of thunder.
The trick is finding the tiny pinhole(s) created in the trailing edge of the airframe where the charge exits. That is usually the only ill effect.; २५/५/१७, ८:५४ PM
Richard म्हणाले...: There's no insulation in the tires when they're wet, and it wouldn't matter anyway. Another eight inches is nothing.

The point is that there will be much better sources than the car for the upward leader such as a tree or a building. Thus the lightning strike will preferentially be between those objects and the cloud.; २५/५/१७, ८:५६ PM
rhhardin म्हणाले...: The times I have been hit flying an aircraft there has been a loud crack of thunder.

Just the sound of what I imagined were breakers blowing, is all I ever noticed.

They always did a walk-around to see what was missing after landing.; २५/५/१७, ९:०१ PM
rhhardin म्हणाले...: The point is that there will be much better sources than the car for the upward leader such as a tree or a building. Thus the lightning strike will preferentially be between those objects and the cloud.

If there's taller objects around, you don't need the tire theory.

Charges are not stymied by a gap. If the road is negative, the bottom of the car frame is positive, and the top of the car frame is negative, just as it would be if the bottom of the car were on the ground.; २५/५/१७, ९:०४ PM

Static wicks, many times, are sacrificed.; २५/५/१७, ९:०८ PM
Richard म्हणाले...: Charges are not stymied by a gap. If the road is negative, the bottom of the car frame is positive, and the top of the car frame is negative, just as it would be if the bottom of the car were on the ground.

That is true, but the car by itself won't be able to provide the large flow of charge needed to create the upward leader.; २५/५/१७, ९:१० PM
rhhardin म्हणाले...: That is true, but the car by itself won't be able to provide the large flow of charge needed to create the upward leader.

It gets it from the ground, the same way that the ground does it without the car, but a little more easily because the car is there shortening the electrical path by the car's height.

Imagine a 2000' metal pole standing on a half foot of rubber. It's pretty likely to get hit, as a thought experiment. Same for a 6' car.; २५/५/१७, ९:२१ PM

Amexpat म्हणाले...: My dad used to say, when we were kids, that you were safe inside the car because of the rubber tires.

I was taught that as a kid. I learned, through long conversations with a lightening expert I had last summer (the guy flies planes into lightening storms to measure their effects) that the protection a car offers has nothing to do with the rubber tires. A car can act as a Faraday Cage, which means that the electricity goes along the outside of the car and not in the inside. The same applies with planes. They are often struct by lightening but passengers inside are usually not effected because of they are in a Faraday Cage.; २५/५/१७, ९:३० PM

Michael K म्हणाले...: I've been hit in a DC8 and a DC9, and the house has been hit, blowing off some shingles across the yard, but no particular noise in any case.

We were in a 737 on approach to SeaTac about 30 years ago when the plane was hit by lightning,

A blue ball of fire went down the aisle but did not hurt anyone.

The instruments were affected and the pilot flew past the control tower so they could see if his wheels were down.

We landed without further trouble.; २५/५/१७, ९:५० PM
Flat Tire म्हणाले...: I got caught crossing a dry lake in Nevada alone on a horse when lightening preceded a still distant storm. Steel horseshoes seemed like the wrong thing to be under me so I let him run faster and farther than he'd probably ever run before. I figured we'd get back to camp sooner and there'd be split seconds when no feet were on the ground. Probably faulty reasoning and not sure if the risk of running outweighed the risk of lightening but we made it. When we got to our camp he got double rations and I got several stiff drinks. I was 60 at the time and nobody in the world knew where I was. Good times.; २५/५/१७, १०:०१ PM
LordSomber म्हणाले...: Working in various fields and having close calls with electrocutions has conditioned me to treat any questionable electrical source with the back of my hand rather than the palm.

Michael K म्हणाले...: "I got caught crossing a dry lake in Nevada alone on a horse when lightening preceded a still distant storm. "

George Crile, founder of the Cleveland Clinic, and his wife were out riding in the early 1900s. They were nearly electrocuted and their horses were electrocuted by poorly insulated underground power lines. He got interested in electrocution and did some good early work on it.; २५/५/१७, १०:१४ PM

I remember learning that if you are actually struck by lighting there is zero chance you'll survive. The survivors are the near misses.

Regarding airplanes getting hit, my wife's father died in a Pan Am plane crash caused by lightning, back in 1963. He was the copilot. I presume that planes are better designed now to withstand lightning strikes.; २५/५/१७, १०:४४ PM

"Lightening" is what happens when you turn on lights. Or when your baby drops. "Lightning" is an electrical discharge -- which can cause lightening if it's dark out. But the bolt itself? NO E.; २६/५/१७, ७:०० AM

Off topic, one of my favorite songs to sing to my kids is Lyle Lovett's If I Had a Boat.

I'd scare 'em by the shade tree,
I'd scare 'em by the light post,
But I would not scare my pony,
