    Nice landing. The constant cockpit checks are interesting to follow. Seems like a lot of work, and the precision required to fly the plane accurately is impressive.

    Fact: Elvis left us all some time ago. Or maybe that was just a rumour.

    The recrystallisation temperature for steel is typically between 400 and 700 °C, beyond which it softens rapidly. It doesn't need to get anywhere near the melting point to fail under load. It also takes a long time to prepare a large building for controlled demolition, and if you did you would typically put the charges at the bottom, not two-thirds of the way up and at a time when the building is fully occupied. Buildings that are demolished by controlled demolition are stripped until they are virtually an empty shell. That certainly didn't happen here.

    I wanted to be a commercial pilot when I was young, but ended up with a career in engineering instead. It was only in later years that I was able take up flying. I really enjoyed the challenge of getting my PPL, was able to build my own plane and can now fly when and where I want. However, while training and in the time since I've also had the opportunity to get to know and talk to professional pilots and realised what a long road the young instructors I knew have in front of them to get into an airliner's left seat, and what they have to endure both financially and in terms of life-style to get there. I don't envy them but also know enough now to appreciate the difference in skill levels between a professional pilot and an amateur like myself. While being an airline pilot no longer appeals to me, I'd love to be a Flying Doctor pilot. Unfortunately, I think I've left my run a few decades too late.

    Learnt with a yoke but much prefer the stick. Was unsure how I would adapt to the stick, but it's very intuitive and direct.

    Are your doubts about whether airliners were flown into the buildings, or more about why the buildings collapsed after the event? Just curious.

    I used an adjustable circle cutter similar to this. General Tools 55 Heavy Duty Circle Cutter. Adjustable 1-3/4 Inch to 7-7/8 Inch: Amazon.com.au: Home Improvement Not too expensive and did a good job, but use a solid bench drill, clamp the panel securely and keep your fingers and anything else you value well out of the way.

    The external surface of a building is not a concrete block but the concrete core is, and the planes did penetrate the building. Also the F-4 did not appear to be loaded with fuel. What brought the towers down was not the initial impact and the planes disintegrating, but the subsequent fuel fire/explosion and heat that destroyed the lightweight steel trusses supporting the floors immediately above and below the impact zone. The trusses connected the concrete core to the external steel box columns, and also provided critical lateral support to the columns. When that support was lost, the heat affected columns buckled and failed, allowing the undamaged floors above to act as a pile driver to demolish the structure. If you want to bring down a tall structure you demolish the lower columns and walls that hold it up. That's what they do in controlled demolition, and that's more or less what happened here, no doubt leading to some of the conspiracy theories.

    Just about anyone picked at random off the street could do a better job. And it wouldn't be a bad idea to move Mitch McConnell on while they're at it. The Senate might actually be able to get something done.

    Hard to see what good he's done. All he's achieved is revealing how divided the country really is and making it even worse. For a failed businessman, he's not a bad politician, but only when it comes to looking after his own interests. For the country and the world in general he's a disaster. The sooner he's gone the better.

    Not to mention a large quantity of fuel added to the mix.

    He seems to think the plane would spear through the building and come out virtually intact on the other side. This Phantom didn't fare too well and while a building is not a concrete block, try hitting it at airliner speeds and see where the energy goes. I don't think there would be much left apart from the entry hole.

    Or maybe just a female passenger?

    One litre plastic acetone bottle (empty preferably), works pretty well, but autopilot definitely helps keep things under control. It's actually a significant safety issue, I think. Nothing destroys your concentration and raises your stress level faster when flying than seriously having to go and not being able to stop and get out.

    Nice work! Enjoyed that. Much more complex than my little weed-hopper.

    I took about 4 years to build mine. Never had a problem with losing interest although on the few occasions I was able to work on it for a week or ten days straight, I needed to walk away from it for a bit. I think the motivation came from seeing everything come together one bit at a time, enjoying what I was doing, and knowing that one day I would finish it.

    Enjoyed that! Keep them coming.

    Plenty of options. I flew from Portland via Aldinga, Port Lincoln, Nullarbor Roadhouse, Border Village, Cocklebiddy and Esperance.

    Yes it does.

    Congratulations! At 43 you should have far more than just a few good years left.

    In the RV-12 the filters are straight off the carb.

    A link to John Brandon's tutorials?
  24. rgmwa
    Thanks. It just looked very deep for a wing spar.

    What's the purpose of the vertical slot on each side of the fuselage? Good to see the project is still making progress.
