Hi John,

what happened?

Andreas

If memory serves me (big assumption at 74) this intrepid aviator waxed
his ship and then changed the safety tape....................it lifted
but didn't come off and caused such a flow change over the elevator
that he (intrepid aviator) didn't feel he had adequate control to try
and land the bird (Ventus B). Soooooooo, he tidied up the cockpit and
stepped smartley over the side!

There's a thread on this with accounts from folks who attended that
event. Here's a quote from John Cochrane based on the report at the
pilot's meeting after the accident occurred:

"I too was at Uvalde. The explanation for the Ventus crash given at
the pilot's
meeting was that there was NO thin tape holding down the mylar -- only
the mylar
itself, held down with double sided tape. It started to separate at
the leading
edge of the mylar, resulting in progressively worse elevator control.
Everyone
went out immediately to check that their thin tape was sticking well
in the
Uvalde heat! "

Sounds like the combination of the heat and the lack of any safety
tape was not a good one.
