Missing Airliner

Anybody know why the transponder even HAS an "on/off" switch controllable from the cockpit?:confused:
 
I think there was an on/off switch for the transponders on the C-9A's I worked on but that has been a long time ago. this was a military transponder so that is a little different than civilian usage. for sure there is a circuit breaker and with a little looking that wouldn't be hard to figure which one.
 
cmort666 has at least a plausible theory the only one I have heard so far..Does explain how a airplane as big as a building could disappear as it is being tracked by radar.....I am beginning to think we might just never know the whole story.....That can't happen...I give you the JFK mystery.....No matter what we think ,we really only have plausible theory's......
 
I'm still going with catastrophic failure of the airframe, either from a bomb or from something the plane was carrying (a la ValuJet Flight 592).

Even if the pilot and crew were incapacitated, passengers still would have been able to get off messages via cell phones or wireless internet unless something large, loud and sudden happened to everyone at the same time.
 
Apparently as reported the transponder can be turned off in the cockpit. There is a Bermuda Triangle out there it's called the Devils Sea. Bring up a map, if they turned west there's a whole lot of nothing but water and unlikely to be any cell phone communication or radar contact, if they had enough fuel they could be sitting on the ice in Antarctica.
 
We know what happened we just can't say because we don't want the world to know what our capabilities are. Our satelltes had to be watching it crash. It's one big cover up like we have seen before. Where's Jessie Ventura on this one? We want the whole truth.

If the friendly signal box was turned off it was terrorism or it was shot down. Either way you can't tell me we don't know about it. It's been almost a week now. Send our CSI guys from our tv shows they can do it in less than an hour right? Where's the real CSI/CIA guru's.

I feel bad or the family members who are waiting for any news and haven't heard one word yet.

No wonder why the drug smugglers are so successful we can't even find a plane. I really think our government knows.

Don't rule out it was a professional hit and they took out the plane to get one person. Cover up?

I don't doubt or count out anything.

If it's not an alien abduction, I'd speculate pilot suicide. At the hand off from Malaysian air traffic control to Vietnamese control switch off the transponder, alter course radically, aim the plane toward the Indian Ocean, set the autopilot, and depressurize the plane. This would require collusion between the two pilots or gaining control of the cockpit somehow.

I don't think cell phones would work unless in range of a cell tower. Also, if the crew was incapacitated due to a loss of pressure the passengers would be also.

Its so its off on the ground so as to decluter ATC radar screens. ATC also requests it be turned off if it starts transmitting erroneous data. That is extremely rare, but it has happened. That's also a reason why there are usually two on airliners.

Here's another.

Al Qaeda has taken over eastern Libyan oil port facilities. This is not fiction. They are loading oil tankers bound for N. Korea. Not fiction. N. Korea has nukes. Not fiction. N. Korea needs oil. Not fiction. Al Qaeda wants nukes. Also not fiction.

So. Is Al Qaeda bartering stolen oil for a nuke to be placed on a stolen airplane? I don't think that's beyond the realm of possibility. What if they could "cloak" the transponders to appear to be another flight? They end up with a 600 mph nuclear cruise missile that could deliver a nuclear air burst over just about any city in the world.

I think the above scenario is credible. The nagging question remains how did they get the airplane, if they did ?

Similar scenarios could be written about Iranian involvement. What better way to realize their goal of wiping Israel off the map than a nuke above Tel Aviv? A strange irony is the Iranians accused the US of "kidnapping the airplane" just the other day and blaming the incident on Iran and the two Iranian nationals with fake passports.

It's a crazy world we live in. I certainly don't put anything past our enemies. We'd be negligent not to entertain worst case scenarios, especially given our enemy's historical infatuation with attacks via aviation. At the same time we shouldn't be so paranoid or myopic that we refuse to entertain the possibility other causes may be to blame when things go wrong.

Also, if they didn't KNOW that the plane had been hijacked, nobody would call to report it.
 
It flew into a time warp and is now back in the last Century...or a UFO beamed it up into its storage bay...or it just flew off into the unknown like Amelia Earhart.


A transponder has an Off, Standby, On, and Ident switch. It is only turned on just prior to takeoff so it doesn't clutter the controller's screen. The transponder will only transmit if it is pinged by a ground radar station, then it will respond with its information. It is simply a transmitter and receiver used for aircraft identification. If someone took over the controls, or the pilots had some bad intentions, they could descend to a very low altitude where it would be invisible to search radars. Radar is only line of sight and does not follow the curvature of the Earth, and its range is limited by the height of the antenna.
