Just to complete the record, it was UA 585 (DEN-COS) on March 3, 1991;
5 crew and 20 passengers were killed.  The aircraft was N999UA, msn
22742, ln 875, a 737-291 (Advanced).  It was acquired from Frontier in
May, 1986, the last of 25 such aircraft.  (Two were 737-2A1(A) models.)

Fascinating.  Most of the speculation has been that the aircraft flew
into the eye of a rotor (much has been said about this on rec.aviation
by folks from the area) which proceeded to flip it.  Another story I
heard, from some United folks, was that there was some difference in
the rudder controls betwee these planes and United's 737-222s, and
that this in some way contributed to the crash.  I can't recall the
details, including whether it was a difference between the Advanced
and non-Advanced 737-200s, or an airline-related change that United
had not yet applied to the ex-Frontier aircraft.

This seems reasonable, and I've heard the same logic applied to
snuffing a report that allegedly recommended the immediate grounding
of Continental (c. 1989) on grounds of inadequate maintenance.  But
the CVR from the Air Florida 737 crash into the Potomac in Washington
certainly made those pilots look incompetent, and the United DC-8 that
went down in Portland in 1978 didn't seem much better.  Indeed, the
latter, as I understand it, motivated a *major* revision of United's
training program.  Perhaps gender-discrimination is a more sensitive
issue, though.

I believe this is unique insofar as the NTSB is concerned.  Robert,
is this indeed true?

Thanks for sharing it.  If anybody else has anything substantial to
contribute on the matter, please send it in.
