Neil Armstrong is still a "name". At a 30th anniversary event near Houston's NASA (at a nearby park) they held a small celebration mostly for NASA employees old and new.
It took 6 Texas Rangers surrounding him to get him through that crowd (he DID shake hands along the way).
He doesn't like to be a commodity and I don't think he signs many autographs today.
Some other moonwalkers are upset. There is a print that they committed to signing (some who signed it have already passed away) that he still hasn't signed (to my knowledge) even though he pre-approved the artwork.
I want my hair back too.
