Dave: Not sure if it was the intake or the exhaust. Whichever it was, it was covered in lagging and theory went this lagging was soaked by the fluid. There was a documentary on TV years ago in which a clever chap from CAA explained how it all worked.
The bit in the newspaper about the doors jamming was nonsense too. The Captain had refused to allow the doors open once the fire service had reported they could see no flames from outside. What finished them off was the Captain's decision to trigger the oxygen supply to the cabin. This can be seen from the photographs. From below, the aircraft looked lovely; from above it was as if someone had taken a torch to the roof. Many passengers dies still strapped in to their seats. The fire must have been very intense and brief (relatively) as, rather than being cinders, many of them looked like overdone roast chickens. Horrible!
The Tristar used to be one of my favourite airliners. One thing I remember about them was the ceiling in the cabin. I believe some airlines took a rigid version of the cellular ceiling while BA had a version with what seemed independent suspension and they moved about, creaking, all the while.

At the risk of getting off topic, the PCA final report on the investigation into the SV163 accident concluded that although the fire had probably originated in the C-3 (bulk) cargo compartment, the source of ignition remained undetermined.

There is no reference to the passenger oxygen masks being deployed, which is the last thing you'd want to do in the event of a suspected fire.

Kelvin D:
It seems this was a common occurrence with that company's vessels. Not only was it a British crew that caused the disaster, it was also a British company that pooh poohed the concerns of all of their Captains when they had demanded door open/closed indicators for the bow doors. These ferries had "clam shell" type doors which opened horizontally and there were invisible to the bridge (unlike the traditional vertical raising doors which can be seen from the bridge when open. Add to that the fact that the Captains had no way of knowing the vessel's draught or even the actual number of passengers carried on each trip, sometimes sailing with more than 1,200 passengers when they were licensed for 630! A horrible read!
I was on a RoRo ship that always berthed next to those ferries and we called them a disaster waiting to happen. They always left port with their bow visir open, always. And they never cared about the speed limits inside the breakwater. It was full speed astern, then normally narrowing avoiding fishing vessels during starboard turn followed by full speed ahead before they passed the mole.
On our humble RoRo we never released one rope before we had all green on the bridge, meaning all gates and ramps were closed and secure and that the locking bolts had actuated the micro switches in a locked position.
A terrible tragedy, unfortunately to be expected.
As for the vessel's draught. Go ashore, walk along the length of the ship, there are painted foot/meter marks bow, stern and frequently center. They could not be bothered.

Is that my seat? Pakistani plane flew with extra passengers standing in the aisle

Really? Insane if true that the PIA 77W took off with 8 more passengers than seats!

Per: I am not surprised by what you say, since reading that report. Did you know that when these RoRo were used on the Zeebrugge run, the port only had single ramps so they coule unload only one deck at a time. So they used to flood ballast tanks in the bow to drop the nose and make the angle between ramp and deck more acceptable. Trouble was the ballast tanks to a little over 2 hours to flood. The trip from Dover was a little over 4 hours, so half the journey was made with the ballast tanks in the process of flooding. Worse yet, when they sailed from Zeebrugge they were still trimmed bow down That bow down trim meant the rules re max loading etc changed and they were basically overloaded every time they left that port.
If you have not seen the report, it is here:

Dave: The formal report was an attempt at a whitewash. My office at the time was in the base of the tower at Jeddah's new airport, working very often alongside the ICAO contingent, some of whom were friends. One of the tasks they asked me to carry out was the transcription of Riyadh tower voice tapes to cassette for onward transmission, along with what I presume was cockpit CVR tapes, to Washington. I have heard virtually the whole conversation from the flight deck. Trust me, the Capatain ordered the oxygen. The flight engineer (an American) said words to the effect of "don't be so bloody stupid!". The response of the Captain was to the effect of "My aircraft. I am the Captain. Those people in there are choking in the smoke.". I think they were his last words in fact.

I don't think you can really class the report as a whitewash. It makes it clear that the accident was survivable were it not for a catalogue of wrong decisions on the part of the crew, combined with poor training of the ARFFS.

I stand corrected on the pax oxygen deployment , though I'm very surprised that this fact has never emerged in the public domain, given that the CVR went to the NTSB for analysis.

Historically there have been a number of examples of planes departing in extremis with many more passengers than seats; the final evacuation of Saigon certainly gave rise to a few well-documented examples during Operation Frequent Wind.

What is different in this case is that it happened in peacetime during normal ops, and from some of the other posts here, appears to have become an accepted de facto solution to overbooking. Worrying.

SV 163

As I recall,
The fire burnt through the wiring to the air con pack controls and/or engine controls.
The cockpit crew could not shut down the engines or packs so the aircraft remainder pressurised.
That's why the doors couldn't be opened.
Also there were more than 20 bodies in the cockpit which would prevent any crew doing anything

No. The doors didn't open because nobody tried to open them.

The cabin crew were specifically commanded by the captain not to initiate an evacuation, and the ARFFS were so uncoordinated that they didn't attempt to enter the aircraft until it was too late.

From the investigation report:

"Consideration of all available evidence indicates that there was little or no pressurization differential between the cabin and ambient pressure at the time of touchdown and that the doors could have been opened immediately after touchdown."

Two items come to my attention in this thread
Many years ago I flew into Beijing from the Tibetan Plateau after a 9 week working hitch. First leg was in an AN2 Antonov ??? Bi plane rotary russian crop duster/pax/ bomber, a real blast from the past wearing airline supplied leather flying Suits and helmets and having had to give the aircraft a bit of a push to unstick it from the apron, pretty cold up there.
Changed aircraft somewhere in central China, age has erased the name..The new A/c was a jet. We boarded and kept an eye out for any spare seats,, unhappilly the A/c was full, waiting for the doors to close I saw a bus load of pax park near the stairs,, wrong A/C I thought,, no way, a full bus load of pax trooped on board and proceeded to squat in the aisle,, or rather sit in the aisle on little stools they had carried on board. My interpeter remarked that this was CAAC standard practice. Once airborne the Tsingtao made its presence felt, climbing over and around our extras I got to the loo. There was no plastic structure on the out board side of the cubicle and there was ample eviidence that one was expected to urinate onto the alloy A/c skin. GLAD to get off.

Before this I was in Saudi. I was a regular in and out of Riyadh. It was very unnerving to say the least, to see that famous A/c parked beside the runway for months, looking as if some one had taken an oxy torch to the cabin and trimmed if off neatly at the window line Apart from no roof the A/c was intact , even the tyres were still inflated.

The PIA aircraft departed over 100 passengers fewer than the certified escape limit of a 777-300ER. Hardly much concern.

I'd be more concerned about getting out of an Air Canada -300ER with 458 seats, personally.
