Why the **** didn't that idiot abort & go around, numpty!
Have a little charity, obviously with your wonderful skills, you have never made a mistake. Obviously the Piper would have gone around if the pilot had X ray eyes and saw what was underneath him.
A slightly similar incident at night killed an student near here.
All it takes is two simultaneous radio transmissions and a little inattention. The high wing masks the aircraft on final and of course the low wing masks the aircraft underneath.
Anyway a good landing is one you walk away from.
