I know what you're saying Henry. It's just that every time I hear
"back pressure" in terms of rocket or gas turbing engines, I still to
this day have the mental image of Prof. Wilkerson standing at the
blackboard, closing his eyes as if in pain and squeezing his hand so
hard the chalk snaps . . . ;-)

He only snapped chalk? You're lucky.

I had a Latin teacher that would throw it... very quickly... at the
blackboard behind your head.

Why would your Latin get upset when you mentioned "back pressure"? g
