Her Grampa Saved Neil Armstrong!

"My grandfather had a lot of stories", writes Katie Mack, "but there was one that transfixed me: about how he worked with NASA and saved the crew of Apollo 11".

Really cool story. Mack's pride in her grandad is justified.

Update:
21/01/2016. "This is About - The Moon and Other Things", by Robyn Williams and Jordan Raskopoulos (14/01/2017) is an extended interview with Prof. Katie Mack (University of Melbourne page, personal website) about her grandfather, Apollo 11 and other things. She herself seems to be a very interesting young lady.
