This service has been available to U.S. Government customers
for at least seven years, albeit not always with AES.  SkyTel
was keenly aware that capturing and decoding their paging
traffic was well within the means of even casual hobbyists.
Note that they don't say it's end to end encryption:
 Messages are encrypted between the device and an encryption server
 at SkyTel's secure network operations center.
And presumably wiretappable there.
Yep.
