T-6 landing on Hwy 41 at OSH

I couldn't tell from the video, but wondered whether his prop was
still spinning when he landed on the freeway. If anyone ever has to do
a similar landing, I should note that in April 2004 a plane with
engine trouble landed on an Interstate near the Concord, CA airport.
The only serious injury occurred when his spinning prop cut through
the side of a van and sliced into a young girl's leg. At first, the
doctors thought they would have to amputate, but were able to save her
leg.

It doesn't seem like there's any good reason to have a spinning prop
when you're landing on a road, and a very good reason not to. Yet, I
can see where cutting the power just before touching down would not
likely be on the pilot's mind.

I assume that in most cases of highway landing that the engine isn't running
or running so poorly that cutting the power isn't an option. If it is
running at all the pilot would want to keep what power he has in order the
retain as much control as possible.

Also just shutting off the engine doesn't stop the prop from windmilling. To
do that you have to have a prop that fully feathers and even then they don't
always stop fully.

Unmitigated bushwa. Most aircraft engines (fixed pitch & CS prop) will stop
the prop at normal glide speeds.

Never had an engine failure, have you?

Not a chance Jim... In every Cessna, Piper, and Beech that I have
used for instruction, I would have to slow to nearly stall in order
to stop the prop. And yes, I did do fuel shut-off demonstations
for all of my students. 3-4,000' over the airport of course. :-)

Every chance, Bob. Back in the '60s when I did my primary training it was
quite common for the instructor to pull the plug over the airport and have
you "make" the field. The prop on the 0-200 150 stopped at best glide
speed.

In the O-300 172 I took into the bridge at Grass Valley with dual mag
failure, the prop stopped at best glide speed.

In the O-470 182 I put onto the dragstrip at Hanna with a blown jug, the
prop stopped at best glide speed.

Sorry, them's the facts.

My experience is different. When I did prop stopped glide testing in the
RV-6, I had to go well under 60 knots indicated to get the prop to stop. And
I fly behind a wood prop which has very little inertia. A metal prop would
have probably windmilled at an even slower speed.

As a matter of fact I have. In a 172 and the prop continued to spin until I
was on the ground and didn't stop until the AS was about 45.

I have, and the prop kept spinning. I didn't know the engine was dead
until I went to add power and got nothing.

That makes it 3 to 1. You might try adding oil now and then.
