Paul,

We agree on most of this HP stuff, but the above statement needs a bit of
clarification.

The force must result in movement in the direction of that force in order to
accomplish work.  And time is not a factor in determining how much work is
accomplished.  Work and HP are not the same.  HP is work per unit of time.

I agree that this is hardly rotary info, but Dave Blanton killed two pilots
that
I know of because he didn't understand the basics.  Dave told them that
they had 270 HP but in reality, they had only 165.  Both crashed shortly
after t/o, couldn't climb.
