This Learjet crash sure looks like an icing situation. They were at 37,000 feet over a thunderstorm and suddenly started descending. There's a transcript of ATC calls that mentions the icing. Ice accumulation is faster on tightly curved surfaces. The tailplane is basically small wings, which means tighter curves, so ice accumulates on the elevator at the back. The ice makes it less effective, you have to apply greater control deflection to keep the nose up, and then you run out of control authority, or push it too far and stall the tail. The nose pitches down and you pick up speed, exceeding limits of the aircraft. The horizontal stabilizer may have been torn off during descent, it would have an IAS of over 400KIAS at this point. That's over the 340KIAS limit. Mach number would be about 0.88, and when you factor in turbulence the stress on the airframe is even worse. So, I expect the horizontal stabilizer didn't come off until the overspeed condition.

Writing this in my personal capacity, but I have been flying these types of aircraft for more than 20 years, with over 8,000 hours, and have reasonable familiarity with how the charter world operates. I feel compelled to post after seeing commentary about the Lear 60 crash, from missile strikes to DEI to critiquing this poor woman’s final radio calls. That last part is what I find most troubling. She was the second-in-command (SIC), and while she was empowered to point out mistakes as part of good crew resource management, she was doing her job, communicating with ATC right to the end in a terrifying situation. She likely knew before many of those calls that she was going to die. I have heard final calls from friends, from military pilots with thousands of hours in fighter aircraft, and they are just as heartbreaking because they know the end is approaching. I understand the public interest given the footage and audio. But you do not know the aircraft’s maintenance history, whether there was a structural failure, if any failure was induced by turbulence, overspeed, or overcontrol, or everything happening in that cockpit. I am sure weather will be part of the investigation, but beyond that, it is speculation. The charter industry routinely hires commercial pilots very early in their careers to gain experience alongside an ATP-qualified captain before they move up to the airlines. She would still have the appropriate training, qualifications, and checkouts by an FAA examiner or designee. Let people investigate, learn, and share the facts. Be respectful to those who perished and the families who carry their memories. God bless them and their loved ones.

It is so refreshing to hear a NASA administrator address issues that have long been these huge elephants in the room, like Orion's inability to reach low-lunar orbit. Everyone knew it was an issue, but no one did anything about it for 15 years. Finally, it's being addressed.

If SpaceX was able to keep the roadster testing at McGregor secretive, I have no doubt HLS has the same thing going on.

SpaceX turned a render that many called a dream fantasy into a reality 2 years ago today with the first tower catch of a rocket.

So basically there's the oxygen injector face which is sandwiched between the oxygen turbine housing on top and the fuel hot gas manifold below. This joint also holds the thrust chamber and the main injector face to the bottom of the hot gas manifold, below it. It's a series of bolts atop the threaded rods holding the stack together that ended up being problematic here. They don't put safety wire on them for some reason. In hotfires on the ground the preload on those bolts ends up releasing slightly. This was not a problem before because the rate that happened was slow enough to not matter whatsoever. It was a problem on Flight 8 because the rate that those bolts continued to unload was greatly accelerated by the then still-unsolved vehicle resonance problem. Eventually it was unloaded enough that the upper end of the seal of this whole joint assembly began to separate, allowing the extremely high pressure hot gaseous oxygen from the OTP above to mix with the hot gaseous methane from the FPB coming in from the side. This blew the engine apart (it was center engine E1, IIRC), and the direction that the joint began to unseal and eject hot gaseous propellant was in the direction of the neighboring RVAC, damaged that neighboring RVAC substantially enough to force it to shut down as well as damaging the lower pylons mounting the rvac to the ship skirt. the stress on the upper, central RVAC mount attaching it to the aft dome and thrust structure, from the center engine explosion and the subsequent unstable shutdown of the RVAC overstressed that mounting fixture and that's how that engine managed to completely liberate itself from the vehicle
