A little theory.

A long time admirer. For me, his "O ring and a glass of ice water" demonstrationwhich kicked the air out of the NASA gas bags during theChallenger Disaster inquiry was most memorable. A remarkable man. 72, Tim Colbert  K3HX

Excuse my ignorance, Tim; maybe I am being naive, but could you explain
to which Elecraft products you are referring? I do not know of any 'O'
rings in any of my Elecraft transceivers.

I believe people are confusing Feynman and Sagan.  I think it was Carl
Sagan who demonstrated the sloppy practices with combination locks and
did the Challenger enquiry.

I did read some of Feynman's lectures, in high school.

Sorry, it is you are confusing the two. It was Feynman on both counts.
Sagan would have been 8 years old when the Manhattan Project was
started. Feynman was also on the Rogers Commission that was tasked with
investigating the Challenger disaster (Carl Sagan was not involved).
