Yes, I believe you are correct, but Clinton classified those in the "National Interest" and they are still classified to this day. No one has gotten a look at them beyond about the second or third day when they copies went to the White House.
Technically, all military radar is classified secret at the least. What Clinton did was forbid releasing the information, which was nuts since it is commonly released to federal authorities as needed. I was on both Flight 800 and Challenger analyst teams. For NASA we helped locate the shuttle wreckage, which was interesting because dear old dad was on the crew autopsy side of that disaster and waiting for that wreckage.
