One data point on the "dive brake open" detection with this particular
accident.

I've started a flight three times where the divebrakes were unlocked
and then sucked out as speed picked up.

In the first, 20+ years ago, it was a Blanik where we were past the
point that we should have lifted off. *I don't know what made me
looked at the wings, but I did and saw them open. *Closed them and we
ballooned up, almost causing a second incident but caught it quick
enough and continued on with an otherwise normal tow.

In the second, 12+ years ago, it was in my Standard Libelle where the
divebrakes mattered little to the Pawnee towplane. *A radio call from
the towplane at about 700 ft. and I closed them.

In the third, about 8 years ago at Minden, I was launching in the
ASH-26E and halfway down the runway well past where I should have
lifted off, I looked out to see the brakes open. *I killed the power,
and slowed down to taxi speed, taxied around back to the takeoff point
for another launch.

After these teaching moments, I now always glance at one wing on the
takeoff roll once I get good aileron control and again once I'm past
the turnaround altitude (400-500 ft.). *It's now part of my takeoff /
climbout procedure, so perhaps each pilot can add this to their
procedures, whether or not there are spoiler alarms on the ship.

Kemp....

Most learn this lesson after only one time! * In fact most learn this
lesson from someone else's mistake...

If you simply do a proper pre flight inspection, a proper take off
check list, and keep a hand near/on the spoiler handle.....it will
never happen....never....100% sure.....(ok...glance at the wing
too.....couldn't hurt)

Then you don't even have to remember the signal, or have a radio....

Right, IF is the key here. If we always do everything right than there
is no need for anything else, right? No need for automatic control
hook, parachutes, seat belts in cars etc, etc. But we human do NOT
always do everything right, and the first thing that goes away when
distracted or in emergency is the checklist!
I find it strange that some people still believe that they are immune
to mistakes since they always use practice, checklists etc, just
because nothing happened to them yet. We need to make the best effort
so mistakes wouldnt kill us so easily.
Kemp suggestion to glance at the wing is a good one, especially if the
tow is not going as expected!
