I flew on a Holiday Airline Electra into South Lake Tahoe years ago.
The approach was a long straight in, of course, and the turbulence in the basin was extreme. Power was all over the map, and on one sink, the Captain firewalled all four. I was sitting F1' just ahead of the left wing.
I don't know from whirl mode, but One and Two were describing circles in the air two feet in diameter at the spinners. I was convinced both would come off the wing. The extension forward of engine and prop on this aircraft is remarkable, and made for some exciting wobble.
Lost at the casinos, naturally.
