That's just the thing. It isn't possible. Whenever something is removed, trace indications are consistently left that it once existed and is now gone. This is true of classified documents, computer data, the works.

Knowing what a pack rat the military is, I suspect you are correct, and something will be found.

However remember that this was largely a computerized operation, and even a few backup copies of terabytes of info can be over written, and the devices pressed into service for payroll records or supply orders. Nobody has time or money to try to go thru every reel of tape, every obsolete disk drive stored in some dusty warehouse on the back lot of some military archives.

I hope the backup copies were not here:

we don't need the raw data - just the final outputs that comprise the reports showing the highest ranking matches.
