The stairwells in the Vienna International Centre complex are quite large and, from the top of a 28 floor building, you can see all the way down to the 3rd level cellar. Each floor is about 10 feet high, so that's quite a ways go go.
A few months ago, a U.S. citizen fell down one of these under suspicious circumstances. There was speculation that it was suicide, but the autopsy indicated that the man was suffering from something like an angina attack.
Thank you Schnucki for the update.
I appreciate it.
