I'm not sure that I am understanding what the cylinder actually did. The article
said that the cy. shot up into the main cabin, hitting the door then falling
down and exiting the hole in the fuselage.

Usually, when I've seen oxy cylinders fail it's been due to a problem around the
neck where a fitting has snapped off. However, in this case it appears that the
cylinder's base may have ruptured, thus ripping the entire bottle away from its
fixtures.

I'm surprised that it was able to fall back through the hole that it made in the
floor, unless it was an exceptionally large one.

Whatever, it certainly did some damage.

Here's a link to the preliminary report on the ATSB web site:

Yes, it does seem a bit of a fluke, though at that point in time, there
would be significant airflow towards the hole.

As said in first post on this incident .

They were/ are bloody lucky

Thankfully the what ever fates have a hand in such things in

Yes Phil, indeed, it did end well. My next query is; what made the O2 bottle
fail? I anxiously await further investigator's reports.

It's OK - I think they're onto it.

Nahh - was Harry Potter astride it - riding it out to freedom.

Doh!

PS You don't think gravity may have played a role?

Yeah, maybe.

Another thing, I read the article in the paper and viewed the photos online. The
hole in the floor seemed significant in size. The newspaper reports (which is
all we have to go on unless the man himself wishes to comment) suggest that the
crew wasn't aware of what damage had been caused til they landed. Now, I'm
wondering if they were able or unable to peer into the hole. If so would they
not have seen the opening in the fuselage?

To Marty, I saw a report on the news last night (Ten, it might've been) where
they had an animated "reproduction" of the events. According to it the base of
the cylinder ruptured. If that did happen then it's not surprising that it took
off like a bullet.

I once witnessed an oxy bottle (oxy acetylene type) fall off the back of a ute.
It hit the ground, the neck snapped off. It then shot down the hill like a
bullet and disappeared into the fog. We found it 100m away half buried.

Scary stuff.
