Gerry Hattrick. There were 2 Pan Am incidents at SYD, A B707 and a B747.
The B707 ingested a number of birds on T/O. Investigation revealed the a/c was slightly over weight due to an incorrect fuel SG and the brakes were not up to scratch.
The B747 over-run was attended by the firees who encountered a Captain shouting obscenities from the window saying he was going to taxy the a/c out of the over-run.
