George,
So
very sad, unstable and inevitable. The box/jack loose combination is
just asking to fold over with the slightest slip or nudge in the
direction of the pilot's foot well. The load path is precarious because
there is so little righting moment to resist lateral loading, combined with the
foldable "knee joint" at the box-to-jack interface. Please use a
taller airplane jack stand assembly next time. Monday morning
quarterbacking is easy, I know, but this should have been
obvious. I'm glade that you were not under it when it tipped
over.

I should have included this photo with
my previous posting. This one shows
the one leg on a jack and the other
two firmly on the hangar floor.
