Not from the evidence so far.

Don't know if you're following the hooha about the Memo's released yesterday that show Lt. George W. Bush defied direct orders to report for physicals, and other such alleged disobeyed orders from the man who would become "Commander-in-Chief", but the best the pro-Bush folks seem to be able to come up with is that the documents are fake.

The basis for this argument seems to be on the fact that a superscript "th" is used, and they charge that typewriters of the day didn't have such an ability. Thus, the documents are fakes created on a Word Processor today, instead of a typewriter back in 1973.

I don't know. But I do know that Josh Marshall discovered a superscript "th" in documents from the Guard that the Bush team themselves released some time ago! So clearly there was a superscript "th" in use by the Guard back in 1968.

If the memo's are fake, it wouldn't seem to be because of a superscript "th" (or a proportional font, which is also a theory that Atrios then quickly debunked here)

Josh points to these .PDF files online as released by the Bushies. The document in question is the first vertical one in the bunch. I've taken a detail of the page in question, and it's superscript "th", and made it a bit easier to find:
