Lizzie ,
I certainly can't argue that a blind pilot is a logical impossibility. But you may find it useful to read the exchange (just below your post to this forum) between Nick Matt and I. It may be more useful to you, in the long run, to focus on functional limitations instead of on categories of disability. When you are talking about things like being a pilot and being blind, there is such an obvious connection between the need to see and not being able to see that the distinction (functional limitations versus categorical exclusion) seems unimportant. And you are right -- there is no reasonable accommodation in such a case. But what about the "obvious" tie between (for example) reading music and being a music major? Blind people cannot read music because they can't see, right? But we know that blind people CAN be successful in careers in music, both performing and teaching. The difference? The functional limitation so clearly at issue is something that CAN be accommodated this time. Focusing on the limitation, instead of the category, allows you to consider that possibility.
