on a tooo short Runway...

The *Genius that had suggested a "180 degree Return to Runway"
Had to be smokin something serious.
This "Plan" seems to have been "Doomed to Failure" from inception.

While the "plan" seems to be seriously flawed, and contributed to the
accident, it may not be the direct cause. Photos and videos clearly
show the right airbrake extended and the left retracted. This points
to a failure of the airbrake controls, which would be consistent with
what most witnesses reported (he veered off to the right after doing a
pull-up). There is an AD out on the DG-1000 airbrake control circuit.
These controls hookup automatically, so an assembly error is not
likely.

If there is in an AD that was not addressed and the bird was
flown, that would not be very good in this matter.

One does a positive control check on this sort of stuff several times
It is my theory the spoliers popped out from the force of the accident
not prematurely as you may suggest. It is nice to blame the
manufacturer
on this sort of stuff however, I have my doubts and the sailplane
should
still be able to manuever with one open.

Nobody is "blaming the manufacturer"; the existence of the AD is a
matter of fact, not fiction.

The wings and the portion of the fuselage aft of the cockpit are
intact, absent of any crushing. In any event, inspection of the
wreckage will confirm or deny the theory, and has probably already
been done.

The ability to fly with one airbrake out in level flight does not
imply the same in a high G pullup. The unexpected deployment of a
single airbrake in this attitude may be beyond the yaw authority of
the rudder. In any event, the pilot could have been confused long
enough that the glider got into an irrecoverable attitude before he
realized what was happening.

No. The plan was for him to do a 180. It was doomed before they even
hit the gas.

The plan was likely for him to land straight ahead after they got

To all you posting on this thread.

About a month ago, I was contacted by e member of the DGA Directors
Guild of America.
He and I are both SAG members and we both have movie manuals to film
this sort of thing.

It is required by insurance.

The director told the production company that he did not want to film
this without anyone
other than me because he knew my background in soaring.

We went thorugh extensive detail about location scouting safety
briefings etc. etc. plans
for the film shoot. For those of you who do not know me, I have about
3000 hours in
sailpanes flew in the worlds a few nationals, womn a few regionals and
am a 2nd
generation sailplane pilot, SSA life member.

You can see some of my film credits at www.americabyair.com. Select
Demo reels.
We filmed the entire lower 48 every city, landmark, hovel, national
park in HD, beta and
35MM. I have extensive flying and filming in Alaska as well. I am
embarassed to admit I
also I fly (whore around) private jets i.e. Gulfstreams, etc.etc.
which makes me a sailplane
pilot sell out. I can remember a day when I had more glider time than
jet time and I see jets
as big fast glider pigs compared to soaring. Enough about me. I say
this because I have
soaring in my veins and I sleep and drink the stuff.

Well after we gave the production company all this data, with
suggestions on how to
do the shoot and we offered to location scout etc etc. We were told
that we were
essentially the 'it team' for this shoot.

Last friday we were contacted, put on hold indefinitely and suddenly
told the production
company had procured another 'it team' to do the filmwork. We were
like Ok easy come
easy go, that is the way these things usually go.

This thursday my team called me as the news filtered down while I was
busy working on some
other mundane task. I was shocked to learn the pilot elected to do
this in a beast on a 2500
foot strip. The problem is obvious. I have done about 4-5000 launches
and about 2-3000 have
been some sort of ground launch. Those who know me know I specialize
in ground launches
and have volunteered for clubs as a chief CFIG for about 20 years. We
have moved from the
days of the steel cable to Spectra. Cars also produce a wind shadow. A
vacuum of sorts.
Gliders do not fly well in a vacuum. Having a vehicle in front of you
sucking the life out of the
wing root area can get ugly. They also are very picky about down
drafts caused by
'fling wings' (Helicopters). One must carefully take all of this into
consideration much like flying
up close behind a B-757, or A-380 (Scarebus). Helicopters, cars, short
runways, there is a lot
going on with little real estate to bail out on and thus, It can get
you into a world of hurt really fast.

A beast like a DG-1000 needs a lot of breathing room like fine wine.
Cars do not accelerate fast
and eat up prescious remaining runway fast. That leaves little in the
event of an emergency or should the
driver have a freak panic attack and stop in front of you at a speed
where you cannot get out of the
way. It is simply not possible at say 50 knots or less. The glider has
mass and energy and is tough
to stop on a dime with a tiny tire. For example in a jet, every 10
knots you add to the vref speeds eats
another 1000 feet of runway. With an L/D of 50:1, or 60:1 you have the
same problem. cases like
Southwest at BUR are all examples of this and there are many glider
example of a pilots inability to
control energy.

This accident did not have to happen. Had the production crew listened
to pilots who have done this
type of work before the outcome would have been far different. I am
truly saddened to see yet
another glider accident. 2011 has been another bad year for accidents.
We need to do all we can to
improve safety.
