Why am I so skeptical of most everything on TV or even in print from the MSM these days!
Surely this piece explains it all!

Something is beginning to smell! JMHO

Hi Everyone: UPDATE: I just read an update about the crash. Now they say it's just "sea trash" ! It's highly unlikely that a jet can get hit by lightning!! My (Late Grandpa) used to be an excellent Pilot knew alot about weather and my Parents are both Pilots. Chances of that is very high. I mean come on! Like you all have been saying it's unlikely with all the weather satelites and technology on the Jet's. Something seems very odd about this whole thing. At first they said the jet broke apart by lightning over the Atlantic. Now they are saying its just sea trash?? I think something unusual happened that they obviously can't explaine!! Don't know what though. I just pray for the passengers. This really remindes me of the series "LOST!!" Isn't that uncanny!! I hope the TRUTH will come out!

God Speed! Amanda Ashtar
BEAM ME UP SCOTTY!

It is unlikely to get hit with lightning, especially the higher you go.

However, it has happened in the past. Usually large aircraft have systems on them (similar to buildings) that, upon lightning strike, passes the current along this mechanism on the outside and harmlessly passes it off. They don't work as well as the ones attached to buildings, because they are grounded and these ones are not, but they contribute to the lowering the chance of lightning strike.

Again, typically lightning strikes occur when you are low.

I don't really know what to think about it, I'm not too sure. I believe that the cargo may just have been sea trash, that's a believable conclusion, I can also believe that they aren't finding any floating debris after so many days. How many days of wave action does it take to reduce styrofoam cups to little bits? Probably not many.

wow 9 pages before I even got here. ,,, and I see the idiocy started only a few posts in.

amazing, absolutly friggin amazing

It is unlikely to get hit with lightning, especially the higher you go.



Lightning can and does extend into the stratosphere. After all it does not all go from cloud to ground and given that this aircraft may well have been in the middle(vertically) of a storm it would be equally likely to have a strike originate above or below it.
Math, science, history unraveling the mystery, that all started with a Big Bang.....BANG!!

Can lighting bring an aeroplane down? I didn’t think it could. :?

Yes it does Jaydees, and I appreciate you calling me an idiot! :)

Now if you'll consider simple vectoring, you'll note that the higher you go the less likely it is that you will be hit by lightning. :)
Q: My daughter is concerned about airplanes flying during thunderstorms being hit by lightning. From what I have read thus far, I understand that the greatest risks to planes flying in a thunderstorm are turbulence and lightning flashes that temporarily blind the pilots, but I have not read anything regarding lightning actually striking a plane in the air.

A: Lightning regularly strikes airplanes. In fact, as far as anyone knows, the odds are that each airliner in the USA will be hit by lightning once a year. (Obviously some would be hit more than once, some not at all.)

But, lightning has not caused an airliner crash in the USA or of a U.S. airline plane anywhere in more than 40 years.

Protection begins with the fact that airliners, and the majority of other airplanes, are made of aluminum, which is a very good electrical conductor. A lightning bolt's electricity flows along the airplane's skin and into the air. As you've found out, one danger is that the flash could blind the pilots for a few seconds, but I've never found any accounts of this causing any problems.

Lightning protection goes far beyond airplanes being good conductors of electricity, and the last airline crash in the USA blamed on lightning was more than 40 years ago. On December 8, 1962 lighting hit a Pan American Boeing 707 in a holding pattern over Elkton, Md. The lightning caused a spark that ignited fuel vapor in a tank, causing an explosion that brought the plane down, killing all 81 aboard.

This led to rules requiring that airplanes have built-in systems that ensure that a spark will not ignite fuel or fuel vapors in tanks or fuel lines.

Then, during a 1980s lightning research project, NASA flew an F-106B jet into 1,400 thunderstorms and lightning hit it at least 700 times. The lightning didn't damage the airplane, but the data the jet collected showed that lighting could induce relatively small electrical currents that could damage electronic systems.

This led to regulations that require aircraft electrical and electronic systems, as well as fuel tanks and lines, to have built-in lightning protection.

As you've also found out, thunderstorms offer plenty of other dangers and pilots try to stay away from them, especially strong thunderstorms. (Related: Why pilots try to avoid thunderstorms).

If pilots try to avoid thunderstorms, how come lightning continues to hit airplanes? A few reasons: All thunderstorms, especially small ones can't always be avoided. Lightning often flashes into the air, and to the ground, a few miles from the thunderstorm that generates it. Finally, an airplane or a rocket flying into a cloud that's built up an electric charge can trigger a lightning stroke even though the cloud isn't producing any lightning on its own.

I've searched the National Transportation Safety Board online database and other aircraft accident databases, and haven't come up with any reports of lightning causing any airline crashes in the USA or Europe since the 1981 crash of a small airliner in Germany that killed 21 people. I also found a report of a Chinese-built airliner crashing in China in 2000 after it was hit by lightning, but no details were available, and I have no idea when the Chinese airliner was built or what kind of lightning protection rules were in force when it was built.

All in all, as long as you are traveling on an airplane built in the USA or Europe or a domestic or foreign airline that operates in the USA, I think the only danger you could face from lightning would be if you happen to board or get off the plane at an airport where you walk down steps and across the ramp into the building. I don't think I'd want to do that if a thunderstorm were around. But, I'd hope that the airline I'm flying on would not want to expose its employees, much less the paying customers, to the danger of being hit by lightning.

In fact, just a few days ago, we reported that flights to and from Denver were delayed because the airlines said lightning that was hitting near the airport was dangerous to their employees. If you're ever on a flight that's delayed for a reason like this, you have no reason to complain.



So much like I said, modern aircraft have systems designed to make lightning a non-issue.
The skin of the aircraft isn't connected to you by anything that conducts electricity, so you won't all get fried, and the electronic systems are supposed to be shielded these currents also.

And no, it wouldn't.

I guarantee there will be probability differentials between the two. :)

This is an area I'm not entirely educated in, but it is my understanding that typically lightning travels either up or down -I believe it's down- with greater frequency then the other. Either way, odds won't be 50/50.

or perhaps the plane was tractor beamed into a mothership... :o

the aliens are sending us a message...we have to stop shooting and downing their surveillance crafts...a war in which the aliens started when they disabled Hubble imo

seriously, Flight 447 has indeed taken a detour into the Twilight Zone.. :shock:

Harems? You get used to it.

I just added a new one tonight. Got a nurse this time. I suppose I should be shot. :D
