  1. I’ve jumpseated on 787’s. There’s no reason to have a hand anywhere near those things, and the basic design is the same as those used on numerous airframes Boeing and Airbus. The switch has to physically be pulled up and then over a detent before being retracted with a spring like mechanism into its new position. It’s pretty fool proof, and would be interesting for this to suddenly raise its head after the airframe has been flying countless hours over 14 years. Also, two defective switches going into the same plane and failing at the same time is kinda stretching things possibility wise.
  2. The motors will relight pretty quickly if they’re already spinning and fuel is added. It takes a while for the APU on most planes to get up to speed. 60 seconds on an Airbus for example.
  3. There was no asymmetric thrust situation. You can watch the video and see the thing never yaws hard to one direction or has the rudder deflect hard to compensate for one engine at takeoff power. The plane will fly and climb just fine on one motor, and will have special procedures in place in the cases where the climb rate is insufficient to clear terrain. Literally no one trains to do anything procedurally related to a simple engine failure below the acceleration altitude in aviation,. A simple engine failure is a very deliberate and considered exercise and there is no rush to get the thing back on the ground. It’s usually overweight for landing anyway. A situation with something like an engine fire is different, but that didn’t happen here. Add to that the fact that the RAT was out and spinning early on suggests that both engines “failed” simultaneously. Those things take a while to deploy and spin up.
  4. I mean, compared to the news….
  5. I knew it wasn’t raining during the crash but thought perhaps beforehand. Checking the weather on that day reveals 0 precip. Damn. Spoofed on a pilot website.
  6. AAIB Preliminary Report Highlights 1. Primary Cause – Electrical Power Transfer Interruption (PTI) During Rotation • During transition from ground to airborne electrical configuration, the aircraft experienced a cascading dual-engine FADEC (Full Authority Digital Engine Control) failure. • Root cause: Uncommanded bus transfer failure due to arcing in the main power relay box (PRB-A), traced to water ingress during pre-flight GPU disconnection in heavy rain. • This led to loss of electronic engine control at rotation, resulting in both GEnx engines rolling back to ground idle within 4–5 seconds. 2. Flight Data Record Timeline • +0:11 sec: Nose gear lifts off. • +0:13 sec: Sudden engine rollback begins. Thrust reduces from 92% N1 to <27% within 3 seconds. • +0:16 sec: Master caution + ENG FAIL L/R warnings. FO calls, “Both engines dropping!” • +0:20 sec: Autopilot and flight control reverts to Direct Mode. Pitch up attitude peaks at 18°. • +0:25 sec: Aircraft stalls at 186 ft AGL. • +0:30 sec: Full aerodynamic stall; nose drops rapidly. • +0:38 sec: Ground impact at 54° nose-down attitude, 174 knots.
  7. I think that’s wish casting. Especially if it’s Israel firing up the Bomb Iran playlist. This is and was being spun as the strike ending this particular flare up. It’s not entirely untrue given Iran’s token response, and possible signaling of where that response would strike so as not to actually hit anything. An adult decision on their end imoho. We’ll see what comes of the new round of negotiations, but the mulligan will end up being limited strikes on whatever remains of the Iranian nuclear program. Boots on the ground or a year long bombing campaign wouldn’t be tolerated. Another hit? Probably so with those objectives, and I wouldn’t be shocked if a link to an assassination attempt was played up for the base. Always better to have them responding to you than the other way around. I don’t think anyone was surprised that B-2’s could make global strikes with large, precision bomb loads. Especially in non contested air space. They’ve been doing that for years.
  8. It sounds like Iran will be asked to give up all nuclear weapons aspirations and material or the bombing may resume sooner than that. And I don’t think the Mossad putting out that they wanted to eliminate the Ayatollah was coincidence. Negotiations will probably be held with a big bag of “Or else” sitting in plain sight.
  9. Well, once you get past the rage bait and actually watch the briefing by the general you learn some interesting facts. It was 6 MOPs down two ventilation shafts at Fordow. Each weapon was fused specifically for its sequence in the drop, and had a warhead specialized for that sequence. The Iranians had attempted to put concrete lids on both shafts that were removed by the first weapon in each case. The final MOP dropped was an all purpose bomb carried in case of one of the bombers failing to drop for whatever reason, one of the bombs failing to hit the target or failing to detonate. Primary destruction was accomplished by blast and pressure wave effects, and the follow on B2 crews reported that the site was lit up like daylight possibly indicating that something inside the facility was burning beyond the explosive effects of a bunker buster.
  10. No, no. There might be something to this Ty Webb assessment strategy.
  11. My only caveat being that I think the golden age has been going on longer than any of us would like to to think.
  12. I would suggest that governments have been brazenly misleading their populaces since time immemorial. That’s this administration, and the one before it and so on and so forth. It would behoove all of us to entertain the idea that we are being lied to even when the lies agree with our viewpoints.
  13. That’s not necessarily how mountains and caves work. They may have collapsed the facilities inside without the rock above losing an inch. Or they may have damaged the building inside with pressure and blast eaves without collapsing the excavated spaces. Or they may have just created a big pile of slag on the outside.
  14. I’m not sure compliance of the “Ima hang onto this weapons grade fuel (or precursor to) just in case” nature is comforting in their hands. Again, I don’t know how close or not they were. None of us, as has been pointed out in this thread, were up all night worrying about Iranian nukes for years on end. OTOH, I can’t think of a time when I or most of the world wouldn’t have been overjoyed to find out that they Iranians have given up their nuclear ambitions for good. They may well be more determined than ever. If so their facilities are at the very least buried and likely damaged to some extent, and much of their military and nuclear program leadership has graduated to fully dead. We’ll see how it plays out until the next thing for everyone to get hysterical about is served up this week.
  15. Having any material at all produced at a facility who’s sole purpose was the manufacture of fuel for nuclear bombs be snuck out is kinda damning on its own.
