Topic: Russian fligh controllers saved 2 passanger liners over the Sea of Japan (Read 451 times)

Not really.

There's no law but instead is just custom for air routes such as these.  Military typically does use transponder codes. 

One possibility is just plain dumb mistakes.  Another is actual broken equipment in the plane.  Many others.

But at one point or another, whoever this was would have "entered the system."

That is off topic, but let me chime in. Russian economy seems to have adapted to the current oil prices, and besides US won't be able to hold them down for much longer without hurting themselves and their vassals.
Human rights record is far better than in the US (except the Wild 90s, when the situation was dire under the watchful American eye).
Russia never - repeat, never - aspired to be a dominant military force. It's always been on the defence. You'll know when the Russian defensive force will be inadequate - that'll be the day when US invades Russia and starts WWIII. So far, though, the parity of force is maintained.

Being world leader doe not mean having a super military, which scares the world into submission. It means being a fair and diplomatic player in world affairs and trades, and leading by example.

You are right 10000 to 12000 is a typical long-distance corridor altitude.
The surveillance flights would normally hold higher to have more coverage. But given that the airplane was flying with a disable transponder and didn't respond to the ATC calls, it is safe to assume that it was a military flight. As to what purpose it had... Anything from a routine military flight of the type "I fly wherever I want" to a planned provocation (akin to KAL-007 that was shot down off the coast of Japan)

It is a curious incident, but in international waters such a thing could happen.  You can bet a number of intelligence agencies were immediately on this one.

I find the altitude quoted, 11000 meters, to be curious.  That's jet cruise altitude.  It's not typical of surveillance flights.  Also, the aircraft was obviously on a standard route, or the other planes would not have had to have been diverted.

Not with cheap oil it won't be.

Of what exactly?

Their economy is on it's knees.  They might be in the right about Syria (might) but the oil price has ruined them.
They aren't the military force people think they are.  They have poor human rights records.  Would you choose to live in Russia instead of say the UK or Germany?

Russian is emerging as a new world leader.

Thats gotta be an UFO by the Chinese.

That may be so, unless the plane flies outside of that ATC radar range.

My primary goal in posting this was this: unless I posted it, you'd probably never know about the incident - it was on national news. Whereas NATO made a lot of noise internationally a year ago when a similar incident happened in the international space off the coast of Denmark.

Diversion of aircraft is done long, long before there is any actual danger of collision.

Radar will show where the mystery plane landed and from that everything about it can be known.

Russian ATC controllers had to divert the course of 2 European passenger liners over the Sea of Japan. The reason for this was an unidentified flying object travelling at 11.000 meters with its transponder turned off and not responding to the controllers' calls.

The liners that were diverted to avoid collision were first KLM flight and then a Swiss flight. The pilot of the Swiss flight also reported about a visual contact with this unidentified object, which turned out to be a heavy 4-engine liner. It is suspected that it was a reconnaissance plane (my guess is: an American one).
