Christa McAuliffe, that was STS-51 in January 1986.
After high school I went to work in a bank. They asked me if I had taken bookkeeping classes in school and I proudly said "yes, I did". Then they asked me if I could forget what I learned in school and I proudly said "yes I can". I got the job. lol.
That's a true story. In banking, "debits" and "credits" are used in the opposite way that a business uses them.
