I'm picking up hints on Facebook that Dave Seib has died at the
Brazilian Nationals within the last few hours. No word on what happened.

It's been a terrible end to the competition here in Brasil with my
best mate David Seib crashing on launch today and unfortunately is no longer
with us. My thoughts are with his family at this hard time and all of his
friends around the world. Dave will be dearly missed by his huge family of
friends here in Brasil and all around the world.. The competition has been
stopped by the entire field of pilots tonight in respect to Dave and his family.
We will miss you.

I am sorry to hear this. I liked Dave and he was gracious to me in
my role as meet director for the 2007 Worlds.
