One thing I read that he did, that might contribute to rumors, he memorized the floor plans of certain hotels and places like that. If you watched him closely in a situation like that, he would seem to be able to see where he was going, if you didn’t know better.
There was a blind girl who saw the flash from the Trinity test dozens of miles away in 1945, at least she noticed something. Must have been pretty bright.
I have heard some blind people can detect flashes.
Blind, like deaf, runs the spectrum from legally blind but still able to see limited distance with glasses, to completely blind, zero vision at all.
And excellent books I read was about a blind man who was in the Towers the day they got hit and hose he got out with the help of a friend and his guide dog.
But interspersed with that story were accounts from his growing up years. It is amazing to see how able some fully blind people are at navigating their environment.
The books was called Thunder Dog by Michael Hingson.

It’s a great book and something a child could read it’s so clean and not woke or perverted.
