More on CBS and 60 minutes' bad journalism:

The only problem was the memo. Amazingly, this guy at the Air National Guard base, Lt. Col. Killian, had the only typewriter in Texas in 1973 using a prototype version of the default letter writing program of Microsoft Word, complete with the tiny little superscript thingy that automatically changes July 4th to July 4th. To do that on most 1973 typewriters, you had to unscrew the keys, grab a hammer and give them a couple of thwacks to make the ''t'' and ''h'' squish up all tiny, and even think it looked a bit wonky. You'd think having such a unique typewriter Killian would have used a less easily traceable model for his devastating ''CYA'' memo. Also, he might have chosen a font other than Times New Roman, designed for the Times of London in the 1930s and not licensed to Microsoft by Rupert Murdoch (the Times' owner) until the 1980s
