    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?

    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.

    SAAA logbook for the aircraft and traditional log book for me.

    … unless it's an RV-12.

    Maybe see if ADFA can offer a way forward? https://www.defencejobs.gov.au/students-and-education/australian-defence-force-academy/what-is-adfa?gclid=EAIaIQobChMI8qXLxuCj5wIVjiQrCh0GCA5xEAAYASAAEgL8sPD_BwE&gclsrc=aw.ds

    Cheaper for you and easier for us. Sounds like a winner!
