Steel? or just metal? aluminium and zinc alloys melt at a relatively low temperature and I would expect them to be found there. I doubt that even in a demolition that there would be evidence of molten steel. Yes, a building's life may be limited but the very idea that it had explosives built into it is outright ridiculous, even moreso than the original concept. https://www.popularmechanics.com/technology/design/a3524/4278874/

So, one might ask where they got thousands of kilos of explosives into town and into the building without anyone else's knowledge and then set the charges in structurally significant places with detcord all over the place in two huge buildings with thousands of people in without anyone noticing something suspicious?

What does the other end look like? If the silver plated stuff has been sitting around for a while the cut end often starts to oxidise creeping up under the insulation. Sometimes you can trim it back a bit to get fresh clean wire. Sometimes not.

Auster? why does it have a label about a nose wheel lock on the dash?

To add to the above, this morning’s article says that they aren’t sure if he actually is positive for cv19, as two tests yielded two different results, and his condition was such that even if he did have it , it may not have been what killed him. Further investigations are being conducted.

This guy hade a complicated medical history and they are looking at possible contact with the infected healthcare worker from Rockhampton. He had been sick for weeks yet his partner who lives with him has tested negative at this stage.

Trade Tools sell a good range of inexpensive hole saws. I believe they have a store at Geebung on the northside. I've had a set for near 10 years now and have used it on aluminium, steel, timber and other things. The only thing that made one blunt was cement sheet. They can also be purchased individually rather cheaply. If you are using this type of hole saw especially in thin aluminium, I have found it useful to drill your pilot then use a solid arbor instead of the drill bit so you hole doesn't wander. https://www.tradetools.com/search?ProductSearch=hole%20 The circle cutters should be available somewhere....I have bought two of them over the years, but not online.

While I won't condone what these clowns did, I seem to recall that a large number of cases were due to well heeled travellers who decided to hold post trip dinner parties. I have no issue with the government taking some action, but those actions need to be well thought out and not the typical "knee jerk" that we got. Legislation needs to be clear, concise, consistent and above all actually address the problem with minimal negative outcome. It has been a "fail" on all of those things. You can use a small hammer to crack a nut, but the govt used a very large sledgehammer. The result was that the nut was cracked, but collateral damage was/is high.

No one was talking about open slather. There are other options between the extremes. It seems that everyone that's fine with locking the country up believes there only other thing to do would be to do nothing at all. If we all lived by the advice of medicos no one would play football, ride a horse, bicycle, motorcycle, fly recreationally, drink or smoke and probably a heap of other things. These are all things I have been advised by various doctors to avoid over the years. I doesn't take much to look at the laws being enforced over the last few months to realise that a lot of them were utter garbage. Nothing wrong with "social distancing", but there are so many examples of "illegal behaviour" that perfectly embody the spirit of "social distancing", but were shut down. If it's ok to head off to the shop where there are a couple of hundred other people all having everything they handle handled by a few checkout operators, it's probably fine to swim in the surf, lay in the sun or camp in the middle of nowhere.

These are places i have seriously considered moving to. Up here Anna is nearly as bad as Dear Leader, Chairman Dan. According to some stats I saw yesterday, the infection rate was already in steep decline from social distancing and that enforced "lockdown" was pointless. Similar results could have been achieved with a lot less economical damage. No one was suggesting just doing nothing, but for the most part the rules in place are unnecessary and silly. that's what people are annoyed about.

Neither do I, but as an ex-RAAF armourer, I've had plenty to do with guided weapons and seen a lot of the damage they can do and the results of a few CFITs in fast jets.

Some of those look like training exercises gone wrong. The paragliders over water in particular. An acquaintance of mine is a paragliding instructor, I can't remember what they call it, but the do it over a local lake when they deliberately upset the canopy then recover to learn how to deal with a collapsed canopy. They receive instruction by radio while doing the exercise. Perhaps some paraglider drivers could elaborate.

There should be a setting that converts the image to make it appear normal. Some people like the "little planet" effect...I'm not one of them.

The feather action requires a set sequence of switching on the Airmaster. I would consider it very difficult to do inadvertently. They are usually set up with a manifold pressure gauge. The Rotax operators manual has a chart for manifold pressure and power with defined limits. Here is a link to the Airmaster manual. https://propellor.com/Content/Images/uploaded/Documents/Manuals/AP3%20and%204%20series%20Operator's%20Manual%20V4.pdf

As previously mentioned, I have a few hours behind a 912ULS fitted with a 3 blade Airmaster. The owner has put a few hundred hours on it so far and it had about 300 on it when he purchased it. It is still going well so far with no obvious issues. I found it easy to operate and fairly intuitive. It has TAKE OFF, CLIMB, CRUISE and MANUAL settings and can be feathered if desired. To my knowledge parts and service are readily available and different blades can be installed (Sensenich and Bolly) if you want a more efficient blade than the Warp Drive. It greatly enhances the performance envelope of this aircraft. Solo cruise is often up around 130 kts or more with full power available on takeoff and climbout.

It is my understanding that in a harsh environment sometimes ELTs have problems with being activated inadvertently.

Wanna bet? I've personally seen (and walked through) a hole in the superstructure of a ship made by a Harpoon missile almost perfectly round. The missile wasn't fitted with a warhead as it was just a test, but still made a hole just like that. There were a few small parts around, but virtually nothing recognisable from the missile.

Quite likely. I imagine someone has tried to pass it off the outer wall. The images you link are the ones I have seen. Plenty of debris and scorch marks where the wings hit .

where is this image supposed to be? It doesn’t look like any of the other images of the Pentagon

The ABC article is a bit sparse on the information, here is the actual report. https://www.atsb.gov.au/media/5777883/ao-2018-077_final.pdf

Given that they are factory Rotax bolts that appear to be standard automotive types, and are plated, I doubt there will be much of an issue. I have not noticed it be be a problem on any Rotax engine I have seen.

I don't know why they insist on adding other factors like low flying when alcohol was involved. Once you've impaired the decision making process the other stuff becomes irrelevant, somewhat like speeding and alcohol. According to a well presented drug and alcohol management lecture presented by a medical professional, decision making is impaired well before you get to the point of physical impairment.

It’s only enjoyable up to the point when you realise the same people vote and raise children. These people often believe the moon landing was fake....no amount of actual evidence will convince them. The believe all the evidence contrary to their belief is fake.
