Short field is one thing Alan but low PCN is another. The 736 allowable gross weight for PCN 30 runways is 77,000lb versus a maximum 156,100lb for PCN 60.
Far too many of NZ's long enough runways have very low PCNs.
For the 733, it's max allowable gross weight on PCN 30 runways is 73,000lb.
You're not thinking of the 732 which had an engine failure and fire at WLG around 1998/1999 ?
I was watching that and the puffs of grey smoke. All looked very tame from my vantage but must have been worrisome to those aboard. Good thing it happened as the take off roll started and not once airborne.
