This is a bit OT.
At Mr.Glen's Memorial Service one of the speakers talked about his relationship with the "computers" (Many of them black women) who,during the pre IBM days,did all the calculations at NASA.
That was still in the segregation days,but it didn't matter,if they could do the job.
Glen trusted one black woman so much that he wouldn't go into space until she checked the numbers the IBM computer spit out.
Now for the O.T. part.
There's a movie coming out in January about these ladies.
"Hidden Figures".
Saw a show on the making of it.
It looks pretty good.
Can't wait to see. Trying to figure out if it's too old for my seven year old granddaughter.
