Only the tapes will prove which runway they were cleared to land on
Feel free to add your theories.
No need to add theories. There was no accident and all participants are alive & well. The tapes are there to be listened to. There is a simple question with a simple answer. If the a/c was held on the ground for 4 hours the answer could have been obtained within that time.
What occurred during that delay? Did the military & local cop shop hold court? They let the a/c & crew depart so something must have been decided. Were the phones between Pisa & Luton burning hot?
