Apparently the flights captain, John Bartels wife had this to say about it on another web site as OZWITCH
Commwealth flying | Neptunus Lex
"You might not recall that my husband was ex-RAN A4. He now flies 747-400. He had the explosive decompression yesterday.
Fun day!
I can give your readers some facts that are solid:
No engines were shut down.
Aeroplane’s controls were unaffected.
Some computer functions and electrics were affected - all 3 ILS shut down and the Capt’s FMC. Antiskid warning came on.
The R2 door alarm activated.
Capt inititated controlled descent from 29K to 10K, which took about 4 mins. Mayday was called (John never ever thought he would have to declare a mayday in his entire career!)
After levelling off, fuel dump of 50 tons was commenced, and plane landed afterwards normally, but used all available runway. Engine #3 was shut down first, then 3 others after and plane was towed to terminal. Passengers disembarked normally via aerobridge.
John praised crew and passengers, who all rose to the occasion.
I have a few pics I can share if you’d like. Let me know, and if any other q’s
