Video from the Air Safety Institute, showing a couple of close calls. Long time ago when I was a little bit younger, I encountered the second scenario almost exactly. I was departing Hillsboro, Oregon (KHIO), and was cleared for takeoff on Runway 2. I looked up at the approach path before I moved and saw a plane on short final to the runway I was just cleared onto!! I politely declined the clearance, and now I am on the Fediverse.
