Was the interview done early on in the show, or later on? In the first season or two the tension was noticable, but later seasons they seemed to get closer.
Professionally, they got along fine, but they were not freinds off camera. They have a huge deal of respect for each other too and in later seasons, that respect was evident in the excitement they showed in the outcome of many experiments.
Also note that a fair bit of that tension that was seen early on was artificially engineered. The producer responsible for that was fired by Beyond Productions. It's probable that he was trying to stir up drama seen on so many other "reality" shows.
i hate you people, not everything is a fucking conspiracy. think of how many people who worked so hard for decades to actually accomplish such an endeavor. like, hey, lets throw away everything theyve worked for because i think im so smart ive figured out the universe. fuck you... sorry for anyone who actually believes in the landing and had to read this. i hope you stopped halfway
