Subject:
.5 Supertiger
Dear Mr. Mcdonald:
Per our telephone conversation of March 21, 1972, I am enclosing an analysis of the thermal decay heat lirnits for the.5 Supertiger.
Both Modes A and B have been included.
=
Due to the fact that this is a modification of the original Supertiger and not a totally new ' ontainer, we are hoping for a speedy review.

(
Should other points develope, please call myself or Mr. Carl King.
Thank you.
Yours truly, i
