Ron, I just ran across that great recording of the last launch of 
Shuttle Discovery.  Thanks again for that.  I tried to go check 
that out but, 20 minutes prior to leaving Tampa for the Cape, 
they had a glitch with the umbilical and the launch was scrubbed 
for three months.  We couldn't stay with my wife's cousin that 
long to wait for the launch, talk about wearing out your welcome!
Regarding scanners, I just sent Sheri Nolan from Whistler a 
reminder of my interest in accessible scanners and she wrote back 
that she had forwarded  my email to her engineer in the Boston 
area who is currently in China.  She said he would respond to my 
email.  I have also forwarded that email to a friend of mine, 
also visually impaired and an inventor type who also lives in 
that area in the hope that he can maybe work with the engineers 
closely as they are in the same area.  Who knows, maybe we will 
yet be able to experience an accessible scanner! Jim WA6EKS
