What percentage of soyuz launches fail?

What percentage of soyuz launches fail for whatever reasons?

Not fail as in crew death, but fail to achieve desired orbit for any reason???


HAVE A GREAT DAY!

Here are the stats that I gathered from the Wikipedia:

http://en.wikipedia.org/wiki/Soyuz_programme


Soyuz Total Manned Flights - (91); (including Soyuz TMA-4 currently
docked to ISS; Soyuz 32 launched manned, landed unmanned; Soyuz 34
launched unmanned, landed manned.)

Launch aborts - (2); Soyuz 18a, Soyuz T-10-1

Failed rendezvous or docking - (8); Soyuz 3, 7 & 8, 10, 15, 23, 25,
33, T-8

Crew killed - (2); Soyuz 1, Soyuz 11

At the end of 2003, the manned R-7 Soyuz record was
89 missions launched with two complete launch failures
(orbit not achieved). The crews escaped during both
launch failures. Non-launch-related crew fatalities
occured during two other Soyuz missions. A few other
Soyuz missions were aborted after achieving orbit for
various reasons.

There have also been a number of off-nominal descents and landings.
Soyuz 5 being the most dramatic of those not mentioned above:

Of course, it isn't clear if Bob is asking about the launch vehicle,
or the spacecraft, or even if he knows the difference. There have also
been various unmanned flights of soyuz and soyuz derivatives
(Progress, Zond, various unmanned test flights, etc).

And as usual, Bob could have found this sort of information with a few
minutes on google.

Gee, Bbo, haven't you done any of your own homework? Or are you still trying
to figure out whether or not you did any homework before posting that what
happened to Columbia was "the worst possible way"?

Have you yet found your verifiable references to show that, had NASA
management actually had the meetings required by protocol, even though they
said suchmeetings would have been pointless, that what happened to Columbia
*would have* turned out differently, as opposed to *might have*? Don't say
you've already answered the question, because you haven't provided *even
one* verifiable reference that answers the question. You're welcome to
provide a verifiable reference to your post in which you included such
references (note that simply saying "CAIB report", which you did, is NOT a
cite).
