[FPSPACE] another Russian launch failure?

Indications are now that the third stage engine shut down at T+421 seconds.
In other words, it was not a core stage/3rd stage separation problem as
initially reported. The Soyuz-2 1B rocket used today uses the RD-0124 engine
in its third stage. This is the first failure of that  engine, which today
saw its sixth mission. Other versions of the Soyuz rocket (Soyuz-U,
Soyuz-FG, Soyuz-2 1A)  use the older RD-0110 engine, so the impact on
upcoming launches may not be that big.  Progress uses the Soyuz-U and Soyuz
uses the Soyuz-FG. The Globalstar launch set for 28 December uses the
Soyuz-2 1A, but officials may still want to delay that launch to be on the
safe side.

TASS at 1401 gmt quoted a source [but not any official statements],


"Judging by preliminary information, the launch vehicle had a failure before
the orbiting unit could separate from its third stage." 

As Bart suggested, this raises the VERY disturbing possibility that the last
two Soyuz crew launches just got lucky.
