As youare usually never one to hold back from making an informed comment I think your frank answer closes this off- we will just have to wait and see although could you say if was an arrival or departure?
Chevvron you are I think correct that it was Pan am and indeed it was a 747-100 (Typo on my part)
I was just curious about this incident because I didnt think it these sorts of incidents happened after take off with more modern high powered engines
