If anyone is interested...

It wasn't the Stearman or FSX Default C172 that botched my Prepar3D. It was a freaking Windows update that coincidentally installed itself the night before!!

I rolled back to before that update and everything is fine. Just fine.

(Back to the Stearman. )

We live very close to the little airport that the Stearman flies out of. Right around 10:15 this morning I heard the unmistakable sound of her single engine. Sure enough, there she was in the clear blue sky, with someone else in the front seat, exactly one week after my ride.
