Cookie recipe for safety:

learning from
other’s mistakes,

That's what this whole discussion has been about, but you still don't
get it. I am suggesting ways to prevent making the same mistake that
these 6 dead pilots made.

You don't seem to believe that dehydration can cause an accident, let
me tell you about some cases where you can "learn from other's
mistakes".

Cal City Regionals, pilot flying an Open Cirrus approached the finish
line at 50 feet and about 50 knots, all thought he would just land
straight ahead, but just after he crossed the line, he pulled up,
stalled and killed himself right in front of the finish gate. The only
plausible explanation is he must have slowely bled off his airspeed,
but didn't realize it and thought he was going 150, not 50. No water
bottle was found in the wreckage. Dehydration can do that kind of
thing to the mind.

Another pilot flying a Ventus B was seen about 5pm, circling so low
that he was casting a shadow and then crashed, still circling! Pilot
doesn't remember anything after breakfast that day. Dehydration can do
that kind of thing to the mind.

Another instructor pilot with thousands of hours in gliders stalled
his 1-26 turning final to an off-field landing about 4pm. He hadn't
had a dring of water all day! Dehydration can do that kind of thing to
the mind.

Food (water) for thought,
