1.You grew up on the "space coast". How did that affect your childhood?
We moved to Cocoa Beach, Florida, when I was 4 in 1953, when the space programme was just beginning. My father was an electrical engineer and worked on the radar that would track rockets. It was kind of a big deal, but every kid at school's family was tied to the space business in one way or another. It was hard to impress! For a year or so before John Glenn became the first American to orbit the Earth, he would sit down the pew from me at church. He was my idol. He signed my Bible. Thirty years later, I was deputy director when he flew on the space shuttle.
2. Why did John Glenn impress you so much?
It was his values. I'm a bit nutty about core values. (John's) were kindness, humility, work ethic and more. He is the only living astronaut of the original seven and continues to inspire me by the way he lives his life. There are many values in my life but some of the important ones are to treat all people with respect and dignity. To cherish diversity - not just tolerate it but cherish it. To live with integrity. It's the most important characteristic of a leader. If you don't have it, people won't trust you. If they don't trust you, they won't follow you and if they don't follow you, you are not a leader.
3. You're an engineer. Did you ever want to fly?
I did join the flying programme in the US Air Force but never tried to become an astronaut. I was quite happy to help design rockets (at Marshall Space Flight Centre) and later, from Kennedy Space Centre, launch rockets. The joke is that with my struggle with weight, and the cost to get to low Earth orbit at $10,000 per pound, Nasa could not afford for me to be an astronaut. I have the most respect for astronauts. It's so hard to be accepted (for the programme). There will be one vacancy for 1000 applicants and they're all the best of the best. A friend of mine, Jan Davis, had to apply five times to be accepted. And that's another value of mine - perseverance. President Lincoln said: "I will prepare, for one day my chance will come." Perseverance got him the presidency too. It is always key to our successes.
4. How vivid are your memories of those early space flights?
Incredibly vivid. I was in a programme where you spent a quarter of your term working, the rest at school. This was 1968 to 1970 and I was driving a rental car picking up all the dignitaries who were there to see the launches. When Apollo 11 launched, I was standing next to the Vehicle Assembly Building and the 7.5 million pounds of thrust created these shock waves which just about knocked you over, then they bounced off the VAB. You're being shaken around by it but it's hard to even describe. You're 19 years old and seeing what you hope is going to land the first men on the moon four days later. You're a part of it. And I have never lost that excitement.
