hi all-

my condolences to shannon's family.  it saddens me and i'm sure the
rest of our community whenever tragedy strikes.

although i do not profess to be an expert in these areas yet, i can
state from personal experience that it does not take an excessive speed
to start a prop windmilling from a complete stop, recently, i did a
tailslide at approximately 10,000 ft msl(intentional) in my extra
300l(lycoming 540-300hp)  at the top of my tailslide i found myself in
total silence looking at the sky and seeing 3 totally stopped prop
blades which caught my attention as i had never seen that before.  i
flopped over pointing straight to the ground.  it took what seemed like
an eternity for the prop to start turning again though i suspect it was
only seconds and around a thousand feet of elevation loss but i doubt
that the ias was much more than 120 kts(and perhaps less) at that time
though i cannot say this with 100% certainty as  i was just very happy
that the prop started turning and the engine restarted!  fwiw.

very interesting threads-learning with every post!
