airnutz,
I got only to the second line before I got stuck. The dentist who invented the mail snatch was Adams not Brown and I am sure the poles were not 54 feet apart. Somewhere in the original Adams system was a funnel or Vee shaped sort of framework on the ground to guide and align the snatch hook in order to properly catch the bag.
True, Dr. Lytle S. Adams was the man and I've wondered why they've not corrected that typo...
it's been there at least 4 years!
Like I said, the link is a general outline to Fulton's work. That's why I suggested
you vette the net and memory stuff against Veasey's papers
I originally was hunting B-23 stuff on the web and ran across the glider stuff and it was a 'passing
interest kinda thing', as was Adams, All American, Fulton, CIA snatches, etc.
I kept these notes in a notebook over the years and it and I are a bit of a mess.
The error you corrected of mine regarding the 7G pullforce was failure of mine to see
a 'decimal point' in the notes. The notes were checked and read .7G pullforce!
I'm a technical kinda guy and over time I've become more interested in the history and technical details of
aerial recovery apparatus. I read an incorrect revue of the of the book,
"The Airway to Everywhere: A History of All American Aviation, 1937-1953"
by W. David Lewis and William F. Trimble, and purchased it last year. The
revue was incorrect in that, it stated there were good technical drawings and
photos of Adam's and All American's developments....NOT!!! But it did have
an reference in the footnotes for the, AAA, Inc. "Air Pick-up Handbook" of
1947, which may have the drawings and photos I'm looking for.
However, there is some very good data in the book which carries one thru Adam's and
All American's involvement developing these devices. This book would probably be very
handy to you in your research...I don't know how correct all of it is, but it's worth having
in order to gain an insight into the early work.
In this book you'll find, as you alluded to, a large scoop to direct the line to the targeted mailbag.
This elaborate 'scoop' cost $3500 to build in the early 30's and you needed one
at each pick-up site. The 54 foot rope and poles were a simplification of the snatch system
in order to eliminate the 'scoop'. This is a simplification, and you'll understand
why when you read the book...I'm unable to find the exact page I'm looking for right now!
Nice chatting with you Sir!
EDIT: for addition and corrections.
