I cannot remember correctly the problem that led to some spacecraft missing the target some years ago.

Mars Climate Orbiter:

That had to be a big "Oh $h|t!" moment!!

I've written code I just COULD not debug before.

I finally threw away what I was working on and rewrote it, this time it worked right.

Eyeballing the old VS the new I could NOT see the difference - they looked the same!

I used a COMPARE function on both sources and the computer found what I could not, a comma where a Dp should be.

test, Test, TEST!!
