Of course, there may be some minor problems that usually happen during any mission. However, mission commanders and flight engineers who are always present onboard the spacecraft are supposed to solve such problems. About my professional relationship with Tito during flight, I would say that I anticipate it to be really easy and straightforward. I would say that he has the right attitude toward his role in this flight. All of us onboard the outpost, including Tito, will be subordinated to him.
Comfort is determined by some other factors.
The degree of confidence does not depend on Tito either, but on the overall preparation for the flight. So, you probably want to know whether I have any concern related to Tito s presence in our crew. I surely have such concern. However, it is related not to our training, its thoroughness or duration. Tito knows everything that he needs to know to perform his particular role in this flight.
