Reagan and Air Force One?

During the week of President Reagan's death and funeral I heard on one radio
station that President Bush allowed the 747 carrying Reagan's body to
Washington DC to be designated Air Force One for that trip. Does anyone know
if this is true. I wasn't able to watch or read as much about it as I wanted.
This would have been the first time that Air Force One was used as a designator
without the current president aboard. The person making the claim was a caller
to to a talk show so I am not inclined to believe it without confirmation.
