The volts.
The jolts.
The end.

Hit in mid-air!

A Texas teen struck a golf ball, which was then, incredibly, struck by lightning. He was out with his friends at Topgolf in San Antonio when the golf ball flashed in mid-air along with a popping sound. His friends screamed while he ducked and jumped back. Fortunately nobody was injured.

One of his friends happened to catch the footage on her phone:

Four people were injured by a lightning strike at the Grand Canyon.
Lightning strike injures at least 4 people at Grand Canyon National Park

... According to information from the National Park Service, someone reported multiple people struck by lightning at the Bright Angel Trailhead at about 2:50 p.m. on Tuesday, July 20.

A 30-year-old man and a 28-year-old woman were found unresponsive, but the man regained consciousness on his own.

CPR and advanced life-saving interventions were performed on the woman, and she regained a pulse, before being taken to a hospital in Flagstaff. ...

Air transport was not available because of significant storm activity, so both patients were taken by ground transportation to the Flagstaff Medical Center. The woman is stable at a regional burn center.

At least two other patients took themselves to the Grand Canyon Clinic for treatment of lightning splash injuries.

Snowdon: Two women hit by lightning at mountain summit

Two women are "very lucky" to be alive say rescuers, after they were hit by lightning on the summit of Snowdon, Wales' highest mountain.

The pair were in a five-strong group by its 3,560ft (1,085m) peak when they were struck just after 13:30 BST.

Llanberis Mountain Rescue Team was called out by North Wales Police to help rescue them.

The team said one woman "was falling in and out of consciousness", while the other had minor injuries.

Both women were evacuated from the summit to a lower slope, before a coastguard helicopter took them to hospital in Bangor, Gwynedd.

Rescuers said neither woman had sustained life-threatening injuries.

Lightning strike kills at least 16 from wedding party in Bangladesh

Group killed as they disembarked from boat to take refuge from thunderstorm

Lightning strikes are common across south Asia during the June to September monsoon, which is crucial to replenishing water supplies but also causes widespread death and destruction.

At least 23 people died on 11 July in Rajasthan state, including a dozen who were watching a storm cross Jaipur city from watchtowers near the 12th-century Amer Fort. Officials told local media that some of those killed had been taking selfies during the storm.

This Florida driver's dashcam recorded the lightning strike that disabled his pickup truck - apparently permanently. The strike didn't seem all that catastrophic in the video, but it seems to have "fried" everything in the truck.
Florida man's truck totaled by lightning strike caught on dash cam

A Florida man's dashboard camera was rolling when a bolt of lightning struck his brand-new 2020 Ford Ranger truck and put the vehicle "in intensive care." ...

"I saw a few people that were just stragglers leaving the beach. And I said to myself, those are the type of people who get hit by lightning because they're just leaving too late, and continued going. Turns out, they weren't the people that got hit by lightning, I was," Foraker told WINK-TV.

Foraker's dashboard camera was recording when a bolt of lightning struck his vehicle, causing it to shut down. ...

The driver, who was not injured, was able to pull over to the side of the road.

The truck, which only had 4,000 miles on it, was badly damaged. ...

He said the truck was in the shop for 40 days while mechanics tried to revive it, but he is now resigned to simply buying a replacement vehicle. ...

Until recently, I had no idea that a vehicle could be struck by lightning.
I mean, the vehicle is a Faraday cage, covered in glass and insulated from the road by rubber tyres.

As I understand it, it's not the rubber on the tyres that provide insulation as anyway the bolt of lightning has energy to travel maybe up to a few thousand feet through the air so six inches of rubber won't make much different rather it's the metal casing of the vehicle itself. The lightning hits the metal, goes around it or conducts it, and carries on to the ground.

It's also a thing called potential difference (PD) that causes electrocution. If a person touches a 240 volt live wire, then it's the difference in voltage between the live wire, them and the ground. It would be 240 volts. If the person was in a faraday cage, the 240 volts would be conducted through the faraday cage to the ground and not through the person. So the PD through the person would be zero.

Or rather that's how I remember it from 35 years ago when during an engineering apprenticeship I did a years worth of high voltage engineering. I saw a faraday cage demonstration via a huge Van der Graff generator in action with a person sitting inside the faraday cage. It was frightening. Along with the other dozen or so apprentices I declined the offer to try it for myself.

My late dad was RAF aircrew. When a plane was struck by lightning in flight, then landed, the crew were instructed to jump from the last rung of the boarding ladder to the ground, so as not to earth the aircraft.

A valid concern? Foaftale? UL?

:dunno:

I always thought that when a plane in flight was struck by lightning that the lightning didn't stop there but continued to the ground?
The physics behind that being that the lightning is a product of the difference in electrical capacitance/resistance (?) between the earth and the clouds, or some other similar science-y stuff (I'm not an expert).
The plane is merely getting in the way.
That being the case I don't see the need for the jumping off the ladder - none of the lightning is going to be stored in the body of the plane, and even if it did, the carbon in the tyres is enough to allow any static discharge to occur upon landing.
Maybe it was just the RAF ground crew 'little joke' with the aircrew, either that or aircrew clothing was made from polyester or some other such man-made material and generated a bit of static when rubbing against the seats in the aircraft?

Aircraft are earthed before refuelling and the cable used in helicopter rescues can carry
a debilitating charge due to static build up.
