I have never encountered "FU" conditions, but I understand that smoke haze significantly affected viz at the time of the crash despite a theoretical good viz.
I have flown into Truckee as pax looking over the crews' shoulders in a Citation X, straight in, downwind onto 11. It's tight, hot and high. I struggle to imagine a "circling approach" in such an aircraft. It does look a lot like a typical general aviation overshoot-stall -spin, I wonder if misleading visual cues due to smoke contributed.
