Fears for 228 as Air France jet vanishes

[PvtRyan]

Hi news channels, the plane is in the ocean, not missing.

Some people are just stupid, if lightning strikes a plane enough it will fry the systems onboard, thus Airbus=ocean.

Hmm, what actually happens when lighting strikes an airplane? Surely, with thousands of planes in the sky and lighting storms occurring constantly, a plane getting hit by lighting should be a fairly common thing?

Airbuses are protected by multiple lightning rods. They direct the lightning away from critical components of the plane. Even if the lightning missed the rods, the electricity will passes through the shell of the plane only. The charges certainly won't go inside the plant. Also, every electronic control system in the plane is protected by insulated boxes and Faraday cages. External variations of electric field and magnet field should not be able to affect the plane.

looks like desmond forgot to input the code again.

Yes. Planes like these have lightning rod on the nose and a sort of protective skin on the front that makes sure the lightning travels along the outside and towards the rear of the plane so that it does not affect vital plane equipment and circuitry.

At least from what I've seen on modern marvels in regards to one type of plane.

They found debris from the aircraft.

edit:I'm not sure about the protective skin , but a property of all good conductors is that the charge only travels on the outside of the surface.

I have a new theory of what happened.

It went boom.

They found wreckage.

Was it behind the sofa?

Air France said the plane, which was powered with General Electric engines, went into service in April 2005. It last underwent maintenance in a hangar in April this year.

You know the maintenance crew is shitting brix right now. I hope they find the black boxes and find out what happened.

Ok, so here's how electrical discharge on the airplane works. There's no "lightning rod" as the lightning will hit anywhere on the airplane anyway (any random objects you see sticking up off an airplane are antennae).

The entire outside of the aircraft is an electrical ground. Excessive static or electrical charge is released via static wicks on the trailing edge of most surfaces. These prevent static electricity (much bigger threat than lightning) from building up by releasing it into the atmosphere essentially. Works the same for lightning.

Lightning didn't kill the airbus flight. Even if it fried the avionics the engines would still work and it could fly back to land safely. Pilots are trained to fly without them.

I know what happened:

In the depths of Brazil, Swine Flu transformed itself, and transformed people into cannibalistic monsters.

The virus could be transfered from person to person through the bodily fluids of the infected.


Air France 447 carried a passenger who had only been confirmed as Swine Flu+ positive after he had left the country.

Air France 447 was destroyed on purpose due to it being infected with Swine Flu+.

I dunno about the cannibalistic monster part, but the rest sounds true.

Seriously dabomb can you contribute ANYTHING meaningful?

The wreckage found wasn't the Air France flight:
