Probably not 1700. But...
The Soviet Union collapsed in Dec '91. One night in Aug '92, we just completed some night air refuel training and waiting for four crews to land and that would the end of the shift. I can still remember that night. At about 2200, the wing king called down and effectively shut down all four squadrons' ramps. Not the runway. Just the squadrons' areas. We were told to get off the flightline and no one was to get out until the wing king himself said clear. Then we saw the cops ran all over the place and it looked like they called up even the off duty guys. The next thing shocked the shit out of all of us: They turned off all the stadium lights. The flightline was all dark. We can barely make out any shape from the lights from the rest of the base.
Then we all heard the distinctive whine of a C-5. Any AF guy or gal who have been on the flightline long enough would learn to know that whine. That C-5 taxied all the way to one end of the flightline that was no longer in use. I know that area because the base allowed the local SCCA club to use for racing and I was in that club racing my IROC-Z Camaro. Then a chain of fuel trucks ran out and for a couple hrs they refueled and do whatever some things to that C-5. That C-5 never shut off its engines. Then the C-5 taxied out and took off. Then they turned back on the stadium lights and allowed us to return to regular duties on the flightline.
For yrs, in our reunions and over beers and pizzas we occasionally speculated about that night. Never had a clue what happened. Then on our 2002 reunion, we met a retired CMSGT who was chief of the Transient Alert group in '92. The T/A group is responsible for meeting and taking care of any visiting aircraft. He told us that C-5 flight engineer said they were carrying nukes from an eastern European country that sold US the nukes. We were:
SOLD...??? 
Eventually, it came out that the former Soviet satellites were short on cash so they were selling anything they could disassemble.
