Watched a 9/11 Documentary...

[candycorn]

None of the cockpit voice recorders survived the four crashes (only two of the FDRs did).

It got me to start wondering why there is only one CVR and one FDR on the planes. I checked and it seems like there is only one of each still on planes; 25 years later. It would seem like multiple recorders would be smarter than having only one.

It would also seem to me that the same technology that deploys an airbag in a fraction of a second could either deploy to cushion the blow one of these devices may experience or eject the device from the aircraft so it doesn’t get destroyed in the building or mountain with the rest of the aircraft.

Does anyone know why there is just one each of these devices on a plane?

The same reason that they won't do anything to increase security of data from flights, is the same reason that government never changed architectural standards for high rise buildings. . . the official story is naught but bullshit.


If you go on speculating about a nonsense narratives, wondering why they don't do things differently, you will be condemned to live your life in a nonsense world.

Thanks for the input.

Anyone else?

Wouldn't do any good. If the one is broken they would all be destroyed. Need Cloud storage (no pun) during flight?

And, you pay for it. Not me. I dont need it and don't care for your bigger govt BS.

1. Anything that would destroy one would probably destroy both.
2. All of these crashes were the most damaging type of crash you could possibly get, rapid impact into existing structures/terrain of a fully fueled aircraft at or near cruising speed.
3. In the case of the towers and the Pentagon, a building then fell onto them. and they were engulfed in fuel fed fires for up to an hour before that.
4. These were older planes I believe, and thus still had their older tech boxes. Modern boxes have less moving parts and thus can survive far more damage, and more weight can be assigned to protection.

True but if you look at the possibility of an “airbag” to shield one or both of them..I think you might be able to save at least some of the data. Maybe not.

2. All of these crashes were the most damaging type of crash you could possibly get, rapid impact into existing structures/terrain of a fully fueled aircraft at or near cruising speed.

True. This is why all of the conspiracy theories about planes “not breaking up” was so bogus...in almost every other instance, the pilot was trying to save the plane; not inflict as much damage.

3. In the case of the towers and the Pentagon, a building then fell onto them. and they were engulfed in fuel fed fires for up to an hour before that.

Again, true. This is why I brought up the possibilty of perhaps ejecting one of them. But, it may meet a worse fate if you do that)

4. These were older planes I believe, and thus still had their older tech boxes. Modern boxes have less moving parts and thus can survive far more damage, and more weight can be assigned to protection.

Good to know.

Another moving part, and it may fly into something worse. Also, it would have to be on the outside of the box, outside the protections or it wouldn't work at all.

Not exactly a new or novel idea to have stuff on the outside of aircraft.

I'm talking outside the protective gear of the boxes themselves. And accidents happen quickly, probably quicker than these things could react.

You also have to take into account accidental discharge. These things have to be automatic and would have to pop off on their own. Plenty of flight forces that could cause a "whoopsie"

The current system works. The modern Solid State nature of the boxes makes it easier to protect them as well as armor them further.

No more tapes, or reels, or other moving parts. Purely electronic at this point.

Well, it didn’t in 2001...so hopefully things are better now.

Because its all you need.

They could have had 100 CVR's on any of those planes. Flying them into buildings at 500mph will result in catastrophic damage to everything with NOTHING surviving such an impact. The fact that even ONE FDR survived much less 2, is a miracle.

How about making planes crash- and/or death-proof?

With all the technology we have, we can't do that?
