The first thing to keep in mind is they don't fly anything secret during the day unless it can hide in plain sight. A uniquely shaped plane wouldn't
fly during the day. A conventional plane with modifications could be flown during the day. [Think of all the documented Groom Lake daytime flights.
They have all been known airframes. This is probably more true for the Tonopah Test Test.]
I've hiked the area around the Tejon RCS many times. It is buzzed all the time by light aircraft. They have a few Long EZ owners out there.
Long EZ's are the biggest source of daytime UFO or UAV sightings. In fact, some USAF bases keep a LongEZ on hand to act like a UAV for training.
