Did the line discharge by arcing to the rock when it was still in the air (and then into the ground), because the rock gave it a conductive “halfway point” that it normally wouldn’t have?

There is a copper wire tied around the rock and grounded to the Earth. The rock is a heavy weight to get the copper to the line, when then faults down the thin wire and evaporates it.

You can do something very similar with an Estes model rocket and a big spool of super fine magnet wire. https://www.youtube.com/watch?v=34NpyA2OuaE

Oh, I didn’t realize the rock had a trailing wire- I thought it was just a rock covered in copper foil or something, and the potential difference between the lines and the ground was so high that just throwing a well-placed conductor was enough to trigger arcing mid-air. A grounded wire makes far more sense for inducing the reaction we see in the video.

Michael Crichton wrote a book about how climate change was made up and had evil ecoterrorists using them to make fake weather.

I'm just going to assume he started making hats as a hobby at some point after his career took off.

They're was actually two bad accidents yesterday, a ferry in Bangladesh got plowed under by a container ship and 50 some died, along with the 130 something in the plane. I thought about linking em but the ferry video is pretty bad since there was another boat pacing it the whole time

With a big enough rocket you don't even need the wire; Apollo 12 got hit by lightning during launch because it was laying down a conductive trail of rocket exhaust straight back to the launch tower.

Mechanical failure to the degree of "tail just fell off" definitely can.

From Bloomberg:

quote:

Instead of gradually dropping by a few thousand feet per minute -- which produces a barely detectable sensation for passengers -- it began falling at more than 30,000 feet (9,144 meters) per minute within seconds, according to tracking data logged by Flightradar24.

Overall, it plunged almost 26,000 feet (7,924.8 meters) in the span of roughly 1 minute, 35 seconds, the data track showed.

The plane’s dive appeared to have halted for about 10 seconds and it climbed briefly, adding an unusual twist to the scenario. But the Flightradar24 track, which is based on radio transmissions from the plane, then showed it resuming a steep plunge.

Given that strange period where it stopped diving, gained altitude and then dove again - could that figure with a mechanical issue or rule out that possibility?

more:

quote:

It’s possible to come up with many scenarios for some type of malfunction, pilot miscues or some combination that led to the plunge, Berman said.

But none of them seem very likely. He echoed what Cox and Guzzetti said: The 737-800, like other jetliners, is designed so that it won’t normally dive at steep angles.

That means it would likely take an extreme effort by a pilot or a highly unusual malfunction, he said.

Many things can cause at least the start of a dive -- from a pilot suffering a heart attack and slumping onto the control column to a failure of the motor used to help raise and lower the nose. But they would tend to be more short-lived or there are easy ways for pilots to counteract such failures, he said.

“You need something to hold the nose down,” Berman said.

With Flight 261 the mechanical failure was not total until the pilots really fought with it at the end. Before that they were basically flying a roller coaster but when the stabilizer completely failed after they raised it to the max it broke loose and they went inverted.

I'd be cautious about using those flight tracking websites to make any kind of analysis like that without some other corroboration. They don't really have the detailed granularity and accuracy to identify very rapid changes, and I've seen some very extravagant claims made in previous incidents based on what turned out to be a small data glitch. It's possible that the plane briefly leveled off, but it also could be something like a single transponder hit not being time coded correctly, or something on the aircraft not reporting correctly while operating wildly outside of its designed tolerances.

Basic storm chasing knowledge says that if your dashcam shows rotating debris crossing the road in front of you, you would be an idiot to keep rolling towards it. Basically, you hosed up if you're that close, and that video is a weird combination of capturing a crazy moment while also revealing that you were in a terrible position.

There’s no way anyone in that plane was still conscious by the time it hit the ground right?
