Well, to be fair, by "modern" I meant "not 1960's", I didn't necessarily 
mean "2011". :-) This was... let's see... 1990 or so?  So maybe they're 
using flash now.

Another restriction is that you have to be able to actually erase the memory 
completely, such as in the event of landing in enemy territory. I don't know 
how well flash erases.
