As someone who is both totally blind and hard-of-hearing, I rely on tactile feedback a lot. I live in Oregon, and I heard that a new exhibit was going to be stationed permanently, so I wouldn't have to travel far. Yet, this website claims that they want to have Space Shuttle Endeavour under maximum conservation:
I was really disappointed because I was hoping to touch every inch of it, including walk inside of it and experience every detail firsthand. That way, if the audio or Braille information failed to clarify something, I could learn how certain parts and pieces moved to accomplish different tasks. People have various ways of learning, and one of them is through interaction and hands-on learning.
A sighted person can watch videos and pictures of how things move, a blind person wouldn't be able to see that, so they would need to be told, both auditory and tactile, how something moved.
I called the science centre's human resources department to file an internal grievance procedure, but I never heard back, so I contacted the US Department of Justice Americans with Disabilities Act (ADA) hotline, who advised me to file a complaint if they didn't have any reasonable accommodations. Under title II of the ADA, all public entities, be it federal, state, local, private or non-profit, are obligated to modify any policy unless there are legitimate reasons to screen out a minority group. So I filed a complaint with the ADA DOJ, but I'm not sure if they will find it in my favour or the centre's favour.
I mean, if I blindfolded you, and I took you to a great place you've always wanted to experience, but when we got there, we learned that you can only perceive it by seeing - You have an option. You can take your blindfolds and experience it. A totally blind person wouldn't have that option, so they would have to either require the business to make an exception, like wearing gloves to avoid getting fingerprints, or something else entirely.
