Best Satellite-Something Commercial Ever

747 Struck By Lightning

>> ^spoco2:
You do all know that aeroplanes are designed to easily take lightning strikes? Because of their metal bodies, the lighting just runs around the outside on its way to ground.
By way of further explanation:

A handful of jets have been blown up by lightning, including a Pan American flight in 1963 that killed 83 people. But scientists have since figured out how to mostly harness Nature's fury. In the early 1980s, NASA (whose shuttle launch pad was struck by lightning the other day) flew a jet into a thunderstorm at 38,000 feet. It was hit 72 times in 45 minutes, and much was learned. Commerical planes are still hit about once a year, by some estimates. A strike typically starts at a wingtip, nose or tail and courses through the skin, which is often made of aluminum—a good conductor. The plane's lights might flicker, but most of the energy just heads back into the sky if there are no gaps in the skin. Modern jets often employ advanced composite materials, which are not so conductive, so metal has to be added to the composites to carry the lightning.



Adding a little information to what spoco2 linked too above. Many things act as a Faraday Cage which if used correctly will cancel out the forces in play,

Hit By Lightning Caught on Tape and the nasty results

Those of you saying that being in a car during a lighting storm isn't safe have no idea what a Faraday cage is obviously. It's not so much that the car isn't grounded (as hey, that much voltage will easily just arc over to the ground), what a car gives you is a cage surrounding you that is made of metal, far more conductive than you, and a path of far less resistance for the electricity... hence, you're safe inside

Unless it's a plastic car.

Then you're fucked.

Which is also why Aeroplanes (yes, we spell it that way in Australia) which start moving to other materials for their skin actually have to insert metal back into them to give a path for lighting to follow lest the plane be hit.

I just love internet know it alls who don't really know anything.

And yes, many people have survived lighting strikes. But yeah, this would seem to be pretty darn fakey fake fake.

IMO, this video is staged. The burns are electrical, but are from being 'grabbed' by high voltage, usually by workers, not during a lightening storm. Cooking like that takes time and high amperage.
When you are in a car, what protects you from ultimate harm during a lightening strike is that the roof and body act like a Faraday Cage, protecting you from carrying the current.
What's important here is what you (or anybody) can do with amateur special effects and a little mild misinformation. We'll probably see some more of this just before November. If you do it right you can change the course of history.

Are Cell phone towers and HV power lines killing us?

Top Gear- Richard Hammond gets hit by Lightning.

That's very cool. I've often thought that you'd be fine inside a car, as I did think it made a nice Faraday cage, but it's good to see it shown... also good to see the car just keeps on ticking afterwards too.
