The article said the floppy drive is kept behind a locked panel. The article doesn't mention if the updates fit on a single floppy or a stack of 20 floppies. I don't see a fundamental problem as long as the data has checksums to make sure that it transferred successfully. I used to get tons of errors on floppy disks transferring data back in the 90's using Sun workstations and PCs. I started making my own checksums to make sure my transfers were correct.
