"Blueskies"
IIRC, on the Cessna Lycoming, the Gauge and the Idiot Light are separate
circuits. If one or the other remains in the Oil Pressure OK state, and
the temps don't rise, you have oil pressure. If they both indicate oil
pressure loss, it is over. Unless you need to travel some distance (over
water, perhaps) perform a forced approach. Don't rely on the fan for
anything.

The video shows him way too high and fast for the fairway. And, if I
read the Terraserver image correctly, that was his only option at that
point.

It looks like they had almost 8 minutes from the time they reported loss
of oil pressure to the time they crashed. They had about 5 minutes from
the time they reported loss of pressure to the time they reported the
engine failed.

I meant the only option at the point the video begins. I may be missing
some information. But the road was a terrible choice and I don't see any
other option but the fairway in his final flight path. And, depending on a
few extra minutes to get to a getter landing site isn't always wise. The
engine can fail unpredictably. If you're over wide open farmland, you might
as head for the longest flattest field and hope you make it. There's
usually lots of options underneath you all the time. Otherwise, pick a spot
and start the drill.
