All I an say in this section is I was most intrigued when I was travelling across Europe on a long and complicated business journey. Turkish airlines (if I recall right, maroon uniforms) had a sign language video for both Turkish sign language and international sign language. I felt so elated and welcome at that moment. I felt at home. Somebody cared for people like me. I have not come across anybody else who has done the same job.

So what I have to say, yes, the measure of the effort what pretty much sums to entertainment and pseudo-psychology, speaks to the consumer masses who are worried when they jump on a plane filled with other 150~ish strangers.
