down 17R. Obviously unacceptable. I did seem to avoid engine damage
apparently by grace and the short duration.

bit into the airstream for solid ram air.

was 96 degrees. Temps down Hotel stayed around 165 degrees to Alpha. I had
to wait for a Grauman to take off. Ran the engine up a bit to verify
mixture. By the time I called the tower to take the active coolant temps
had gotten to about 185.

the power a bit to maintain 60 ish knots took a mental breath....and raised
the nose. The nose actually lifted  Holy crap....that is almost flight. I
brought back power and the nose settled (uh, by settled, I mean bounced
;-)).

when I checked the coolant temp just as the nose was down, the coolant temp
had DROPPED to the high 170's. A drop. Imagine that!!!

90's today.
