Oh dear, just a couple of slightly inaccurate details, regarding -HK.
Although the TriStar can indeed 'land itself' (and quite superbly, too) it did not do so on this occasion, as the runway (12) was not served by an ILS.
No autobrake either, the SV regular line TriStars were not so equipped.
The Flight Engineer had the pressurisation mode selector in standby and as such, the outflow valves did not open automatically, as they would normally do otherwise, after landing.
Therefore, the doors could not be opened (acft pressurized) on the ground with the engines still running, which they were.
The aeroplane touched down normally, and exited the runway near the end.
Fire services were on hand quite quickly, and it is suspected that the FD crew were rapidly overcome by smoke and fumes.
Were mistakes made by the crew?
Undoubtedly so, however the finer points are somewhat obscure, and were the subject of a detailed review by SV management, with adjusted crew training procedures as a result.
