Rinc

The rigger should always ask first before doing work that is not pre-approved. Same as auto repair shops, which if they find additional work that needs to be done,they have to get permission first.

Maybe if the ship was going down like the Titanic, but then, you wouldn't want to be in the wind tunnel at a time like that...

It does seem like Bernoulli's principle would cause the flyer to stay in the center. At least in theory. I disagree. Let's say the ship tilts 5º to one side. At that point, the wind flow is 5º off of perpendicular, but the pull of gravity is still straight down. I.E. the wind flow is no longer aligned with the pull of gravity. So gravity is going to pull the flyer down at a 5º angle relative to the wind - like being in a track position with the upper body tilted downward. And the jumper will slide towards the wall on the downward-tilted side of the tunnel. If I could draw a picture it would be a lot easier to see. But I can't draw... Imagine that ping pong ball balanced in a column of air from the hair dryer pointing straight upwards. Now slowly tilt the hair dryer to one side. What's going to happen? The ping poing ball will be blown off to the side in the direction of the tilt. In all reality though, a ship that big probably is unlikely to be tilting much, and the flyer will likely be unaffected by such things.
