I heard on the news a few nights back that they have found serious
flaws in the Shuttles Main Engines as well (not the SRBs), and had
that been known, the shuttle would not have been allowed to fly. It
was something about poor quality metal in fule pump turbines.
I have not seen anything in the papers about this, anybody know
anything?

| 175.1 | From Vandenberg, perhaps | SKYLAB::FISHER | Burns Fisher 381-1466 | Mon May 12 1986 14:50 | 10 |
The only thing I have heard is that they are having lots of trouble
certifying the SSMEs for 109% power, and that this power is required
for launching from Vandenberg into polar orbit. Thus, I would believe
a statement like "A Vandenberg launch this summer would not have
been allowed even without the Challenger explosion." Incidently,
there are also questions being raised about the new composite SRBs,
which are also important for polar orbit launches from V.

AWAST seemed to indicate that questions were being more than just
raised about the composite SRBs, and they are considering having
the attitude of the shuttle changed on liftoff to save enough fuel
for the launch of a payload that cannot be launched without the
weight savings from the composites. So the astronauts would get
to ride on top rather than on the bottom of the External Tank to
possibly save enough fuel to get the desired thrust to compensate
for not have the weight savings of the composite boosters.
