I would say the most help I got was from my dad. My dad is a civil engineer in Switzerland; he's 90 years old now, so he's no longer active as a civil engineer, but still a very active person.

Claude Nicollier (born 2 September 1944 in Vevey Switzerland) is the first astronaut from Switzerland and has flown on four Space Shuttle missions. He took part in two servicing missions to the Hubble Space Telescope (called STS-61 and STS-103). Nicollier retired from ESA in April 2007.
