Preconceived notions

Maybe Eileen Collins is a Roller-Coaster phobic but so are many astronauts. It is well known that many in the astronaut corps do not like to fly inside the KC-135. One of the reason is that space sickness experienced while in orbit has nothing to do with the type of problems one can develop in the KC-135. In effect, it is known that people who are not sick in the plane can become very sick in the space shuttle.
