Hoping they would be unblocked but they are indeed blocked.
They may not be blocked, just not requesting radar services.
More than likely… I thought it was not only weird but unusual as I was washing my car to see a DC10 departing with a left turnout from 4R, when the 22s were in use!
That’s what you get for washing your car.
Firefighting aircraft get very good treatment from ATC, similar to air ambulance flights.
There was one along with MAFFS 5 & MAFFS 6 at KMCC in the early evening. I was listening to TRACON and KMCC approach on liveatc.
