There is no wing tank fracture as I presumed, Facthunter is on the money, the fire was obviously fed by the fuel manifolds. The engine aft pylon lugs simply failed, they just broke right through the lugs, and with that support gone, there was absolutely nothing to stop the engine departing the airframe. A very simple, single point of failure, that should not ever have been allowed to pass certification. The lugs had been cracked for some time, and the cracks simply progressed to total failure of the lugs. The airframe was high hours, in excess of 92,000 hrs, and the mandated pylon inspection was determined to be at 28,000 cycles, but this aircraft had only done just over 21,000 cycles, so, as Blanco Lirio says, this inspection period is almost certainly going to change. The interesting point that Blanco Lirio raised, is how gyroscopic procession from the engines rotating components produces increased forces on the engine mountings, right at rotation. The greatest forces applied to the mountings, right at the worst possible moment.

Blanco Lirio is dissecting the preliminary NTSB report, released 20 Nov.

I erred in my previous opinion that the aircraft was on fire before the engine departed the airframe (based on the previously-available limited video footage). Blueadventures photos show the engine departing the airframe first, followed by a rapid outbreak of fire. However, I stick by my original opinion, that major structural failure of the wing fuel tank, caused by the engine departure, resulted in the huge fire. It's amazing to see how instantly the major fire erupted, which could only have been caused by the hot engine exhaust gases at full throttle, penetrating a wide gash in the fuel tank.

You mean you lashed out and bought stainless-steel cable ties?? 🤩

.......make you wish you never came to W.A." Abfullahi grimaced. "Dis sounds like a lotta BS to become an initiated West Australian? Can't I just buy the initiation? I got CASH!!" At those words, OT's ears pricked up. Here was a man after his own heart, who knew how to cut a deal and still keep everyone satisfied. "I'll see what I can do", he said to Abfullahi. "It will likely cost you about 5 new Landcruisers, 28 cartons of Emu Export, a box of bongs, about 15 kgs of weed, and you'd better not forget that..........

Abfullahi couldn't make head nor tail of this message, simply because it was AI-generated, of course - and he sent a message back to OT, saying, "What iz this smooth butt crap, Bro?

OT assured him he was, and then mentioned, "We got Uncle Morton, Aunty Joan, Aunty Tilly, Uncle Mick, Aunty Jack, and we even got Uncle Wiremu, because he's specialised in initiations and tattoos all his life!" Abfullahi was startled by this message. He messaged OT, "Tattoos, Bro?? What kind of tattoos iz in this initiation?? Dis iz da first I hear of tattoos?? I don't like dose needles!!" OT messaged back, "You don't have to worry about Wiremu and his tattoos, but you gotta watch out for Aunty Jack, 'cos he'll.....................

It looks to me like you'd get a sore or strained neck in a relatively short space of time!

The last thing I'd want in a cramped cockpit is a radiator carrying coolant to and from the engine. Too much potential for leakage, burst hoses, split seams, etc. The exhaust system cuff gets my vote.

Apparently there are three types of materials used in C-130 propellers - steel, aluminium, and composite (on the C-130J). Part II on the website below goes into detail about the various C-130 propeller types.

Nev, the C-130 propellers are made of aluminium. In the U.S. Navy KC-130 crash, the prop maintenance was done by a civilian repair shop, and there was insufficient corrosion inspection, and the shop painted over the corrosion. As you'd know, corrosion leads to stress cracks and eventual failure.

The U.S. Marine Corps had one of their KC-130's crash in a similar manner in 2017. It was determined a corroded prop came off and went through the fuselage, causing a chain of structural failures in the fuselage, which resulted in the fuselage breaking up into multiple sections. The C-130 can be stretched by inserting hull sections, and it appears these joins in the hull make for structural weaknesses which are the first point of failure in any mishap or overload condition. Investigation: Corroded Propeller Blade Caused KC-130T Crash - USNI News NEWS.USNI.ORG The Marine Corps determined that a corroded propeller blade that came off mid-flight was the cause of the July 10, 2017, crash of a KC-130T transport plane.

.......an outstanding dislike for the British. Now this French trait became a major problem for Turbo the day he landed in gay Paree (that's gay as in "happy", dear NES readers, just to clear up any misconceptions). The instant Turbo started practising his French, he was automatically identified as British, due to his accent that came from his finishing school training. Not many know that Turbo is a graduate of Eton, and as such, can claim to be on first name terms with many world leaders and people of distinction. It is unfortunate that Turbo ended up selling himself short on his Eton education, by going into trucking and car racing, where he developed the thousand yard stare. It's well known, that if you spend a vast amount of time on the edge, you develop this detachment known as the thousand yard stare. As Turbo tore around raceways, skirting with death and destruction every second, he developed the stare, and the detachment that comes from men who have been pushed to the edge of their limits. Trucking gave him white-line fever (also called "highway hypnosis"), which led to Turbo having huge gaps in his memory after travelling Melbourne to Perth in those dreadful International trucks. Fighting to stay alive on the dreadful highways of Australia (Victorian ones in particular), left Turbo with increased levels of the aforesaid afflictions. Then Turbo took up flying, and this only exacerbated his afflictions, as he left many a flying instructor white-knuckled, as he took aircraft to their limits. just as he did with race cars and trucks. So when the French started to treat him like a British idiot, Turbo's afflictions came to the forefront again. He addressed anyone French with a monotone and a stare that was unnerving, to say the least. Then came the day he...........

I believe Orv is in Eagle Creek, Oregon, so he just needs to keep out of Californian airspace, and he'll be just fine with his Hirth.

Yes, it does by a few degrees, enough to warm the fuel a little, but not enough to damage anything in the airframe. See "Ram Rise" in the link below. Interestingly, air data computers have to measure the temperature rise, to compute TAS exactly. Over Mach 1, the temperature increase on an airframe is rapid. https://en.wikipedia.org/wiki/Total_air_temperature

Doesn't everyone enjoy watching a good drone kill? 😄

Looks pretty fake to me.

The interesting part of the whole deal is the engine pylon pulling right out of the wing structure. The engine and pylon left the airframe complete, but the pylon only separated from the engine after the engine hit the ground. All the previous reinforcement instructions for the MD-11 engine mount area were to strengthen the section of the wing structure where the pylon attached. It was jiggling and pressure from the forklift operator as the maintainers reinstalled an engine complete with pylon (against manufacturer advice) that caused stress fractures in the wing structure where the pylon mounts were attached, was what caused the Chicago Flight 191 crash. This UPS MD-11 was fully stripped and rebuilt from the ground up in 2006, in its conversion from a passenger aircraft to a freighter. The airline industry calls it a D-check, and not a single item in the aircraft is left unchecked. However this aircraft recently underwent a major fuel tank crack repair job, that took 6 weeks to carry out. The fact that the job took such a long time, indicates some very major work was required, and no doubt investigators will be poring over the crack repair records. The major factor in the crash is simply that the aircraft was well and truly on fire, before the engine departed the airframe. This appears to indicate a wing tank structural failure of some kind, as the level of fire is major and it would've had to have been fed by a large volume of fuel that could only come from a fuel tank rupture.

Sorry, Skippy, but not only is Thrusters "theory" plausible - it's not a "theory", it's basic science. When a centrifugal or gear pump sucks, it creates a low-pressure area at its inlet, and the higher atmospheric pressure on the liquid's surface pushes the liquid into the pump, to try and equalise the pressure each side of the pump. If you've ever tried to get a centrifugal pump to extract water from a well, you would know the maximum depth level you can draw from, is around 8 metres (approx 27 feet for us old timers), and the absolute maximum well depth you can draw from, is 10.336 metres (33 feet), by using a vacuum assist pump primer. This is all due to the fact that MSLP can only lift water to those maximum heights before the water pressure equalises with MSLP. A jet venturi pump can lift water from much deeper levels, but this requires a pressure pipe going down the well to the water level, where a housing that uses a venturi effect, utilises the pressurised water from the surface pump, to provide additional water lift ability. If the surrounding air pressure is zero, a centrifugal or gear pump cannot work, because it needs air pressure to make it work. A vacuum cannot "suck", it simply relies on external pressure such as air pressure or gravity, to provide that pressure, to move the liquid to the area of vacuum - i.e., the area of low pressure. If the fluid being pumped is located in a reservoir considerably higher than the pump, then gravity can be used to supply the fluid to the pump inlet. However, for small quantities of fluid, and small diameter supply lines, a lack of weight and the internal restriction in a small diameter supply line, can often mean there's little pressure at the pump inlet, so the pump ends up being starved of adequate fluid to pump. https://www.completepumpsupplies.co.uk/resources/why-cant-water-be-lifted-above-10-metres?srsltid=AfmBOor_On-I8TC5d_1nb21mtLvS2jXI1eu4K8qYddEXsf41KhTw947w

A crashed light aircraft was discovered in a paddock on Nullagong Road, near the Cobb Highway, about 30km north of Hay, late on Wednesday morning (05/11/2025). Emergency services located a critically-injured 39 year old pilot in the wreckage. He was transferred to Hay Hospital, then flown to Royal Melbourne Hospital, where he passed away yesterday afternoon. NSW Police say a report will be prepared for the coroner. No further information appears to be available as to aircraft make or model. https://www.police.nsw.gov.au/news/news?sq_content_src=%2BdXJsPWh0dHBzJTNBJTJGJTJGZWJpenByZC5wb2xpY2UubnN3Lmdvdi5hdSUyRm1lZGlhJTJGMTIxNzY0Lmh0bWwmYWxsPTE%3D

There has been an utterly disastrous crash of an MD-11 cargo aircraft on takeoff in Kentucky. The fully-loaded and fully-fuelled aircraft departing for Honolulu was fully on fire even before it left the runway. The MD-11 barely got airborne before crashing into a petroleum recycling facility and an auto parts store, and the travelling wreckage also impacted what appears to be several hundred parked vehicles. Initial reports are the crew of 3 did not survive, and authorities are saying the death toll is expected to rise, as they find more victims that were on the ground when the aircraft came down. The blaze is enormous, it's reported the aircraft was carrying 25,000 U.S. gallons of fuel (95,000 litres) and the fuel tanks have obviously ruptured in a major fashion, spreading the fuel far and wide, along with the aircraft wreckage. https://www.reddit.com/r/ThatsInsane/comments/1oomplt/ups_cargo_plane_explodes_while_taking_off_in/ https://www.instagram.com/reel/DQp1BJDiOgk/ https://www.instagram.com/reel/DQp0dWlCGic/ https://www.news10.com/video/plane-reportedly-crashes-at-louisville-airport-igniting-blaze/

Nev, I think Danny was being somewhat literal when he said "my" Muira. The Muira block photo that Danny provided is from a Californian owner, and details his MAJOR engine reconditioning operations, which included quite a number of modifications to improve the original design.
