My personal favorite, in a goulish sort of way, remains the
Southern Airways Flight 242 crash in 1977; in which a witness heard the
roar
of the jet engines as the DC-9 glided past--even though both engines had
been inoperative for some time due to FOD.

I have never had an engineless DC-9 glide past me, but I have had
lots of
engineless sailplanes zoom past me and guess what? They sound like jets,
only
not so loud. I imagine that flamed-out DC-9 going by at 100+ knots also
sounded
like a jet, only not so quiet.

As does a Cessna 150 with 40 degrees of flaps, at a level between the other
two.

However, my point is that what the observer believed he heard was not what
he really heard--from which I am making the inference that we have little
reason to presume whether the Lancair was suffering a series of compressor
stalls.

Regardless, a compressor stall would not cause the airplane
to drill a crater into the ground. This accident sounds to me like a
total loss of control, either through spatial disorientation leading
to a spiral that may or may not have resulted in structural failure,
or a structural failure arising out of extreme turbulence encountered
in the thunderstorm.

I should correct myself: a previous poster mentioned rain
squalls, not thunderstorms. When I hear the term "squall" I think of a
squall line, something light airplanes should stay well away from.
It's caused by a fast-moving cold front and can be deadly. I don't
know if this is what was happening there.

Anybody ever hear a Piper Arrow go by on short final with the engine
idling? It sounds like a jet!

Any Piper with a "Warrier" wing whistles just as you say.

Have a great one!

Looking at the recaps on AOPA sounds right on, in fact fuel starvation
is close to the #1 reason for downed aircraft due to apathy,
procrastination, and experience. Yes experience. There are way too
many accidents where the PIC was a seasoned ATP and got himself into
trouble doing the wrong thing with the right aircraft, or a
combination of the two.

Have a great one!

idle.)

A turboprop sputtering? :-)

Reportedly newly instrument rated. Loss of spatial orientation,
stall/spin?

Ron Lee

Who knows. I would expect someone with a new instrument rating to be
pretty sharp.

I was by far at my most proficient at that point. I had an instructor
who had me flying right down to minimums in real IMC for a good
portion of my training.
