Um... no? A voluntary half-day voyage in comfortable seats is not even nearly comparable to the inhuman horrors experienced on slave ships. There is absolutely nothing dangerous about this.
Im a huge fan of the 5th element strat. Slide me into a pod and render me unconcious with gas. It solves so many problems - entertaing self in flight, listening to the bodily functions of strangers, crying babies. Airlines would save millions on meals not served and stewards not serving them. It even solves security concerns, terrorists cant hijack a plane when they are unconcious and locked in a pod.
And if the worst happens, and the plane has a case of engine-rich-exhaust and is hurtling down into the freezing southern ocean, I really dont wanna know about it. Just let Posiden take me in my sleep.
