Hang on. I'll go look.
Many years ago, spending a boring night as staff duty officer, I got about a dozen calls reporting UFOs.
I called the local USAF radar site as well as tower, OSI, police, etc.
When I tried to recontact the radar installation I got a busy signal, then nothing.
Later, after an aspirin and cooling off peroiod involving several more reports; I did get in touch with the radar guys.
They'd all been outside looking for the flying saucers.
