411 and all,
Tried to find the NTSB link to the PanAm 747 SFO accident without any luck....As I recall, that aircraft went through the approach light stanchions at the opposite end of the runway.
One or more penetrated the fuselage. I believe this accident paved the way into research on frangible approach light stantions.
Yes, the aircraft was repaired and I believe is still operating (UPS).
