The P51 was placarded against exceeding 15 sec inverted - primarily oil
frequently our hot jocks in Japan would expell a huge stream of white
smoke, but
no damage after a full flight line inverted Buzz job (Kisarazu 1947)

Are you out of the hospital Vance? Can you make it over to SZP
tommorrow. We are working on Alex's airplane trying to make it cool.
Paul Lamar
Yes I am out of the hospital but still on a short string - The day after I
got out I had to put
Emily into the Pleasant Valley hospital with pneumonia. I did get over to
the Camarillo
airport to watch Rich's plane being loaded on its way to El Salvador See pix
That really is me in the blue shirt
Vance
Hope everybody gets well soon.
BTW how is your mill working?
I may need some stuff milled.
