I believe you are repeating wht I have said. I said that "dragging it

However: ormal and short field landin gin the Bo...F33, Deb, and A36
(IF flown according to the POH) are all at well less than maximum
endurance. This is far from dragging it in which was giving the ASF
fits about "dragging it in for short field landings" which are flown
well under max endurance speed, but are "steep". The short field is
just steeper with more power. However in neither case should the
plane be in the so called coffin corner as there is enough reserve
power to stop the descent without lowering the nose. That is even
flying a very steep short field approach.
command or if you will behind the power curve. This is absolutely
correct. Coffin corner is the area behind the curve where sink rate
can't be stopped with power but requires reduction in angle of attack.

Any of the Bo's get really squirley when flown this way and for a
competent pilot will provide suficient warning, but I'd sure not want
to get one that slow any where on final as that sucker is so close
to stalling the unwary could quickly ruin their insurance companie's
day.

For a perfect example of an aircraft in coffin corner, see the Edwards
AFB accident involving a young AF pilot who got his F100 so deep into
coffin corner behind the curve he couldn't recover the airplane; not

That was one impressive film strip. Although it w asn't long it sure
seemed that way. He did one whale of a job balancing on the tail until
she finally fell over to the left as I recall. When I say balancing
on the tail, for those who haven't seen the video/film clip he wasn't
just nose high.

enough air under him to reduce the angle of attack. He applied full
burner but couldn't fly it out on power alone. Reduction of angle of
attack was what he needed and he didn't have the room. THIS is the
definition of coffin corner and it most certainly IS in the area of
reverse command.

Which reminds me, I saw a clip of a 104 where I believe the engine
seized. It started to skid sideways and then *flipped" over onto its
top. Do you know the story behind that?

I thought coffin corner was the point where if you go slower you stall
and if you go faster you hit critical mach number?
