    Air India 787 crashes on take off

    The report noted that on 737's there was an AD where apparently some of the switches did NOT have the "pull switch out" locking feature. The report speculates that a similar model switch is used on the 787, so did these switches actually have the locking feature? Specifically, this paragraph:

    Air India 787 crashes on take off

    Well, if something fell on the switches and cut off the fuel and I was the pilot, I would definitely reach down and try to re-light the engines... So, that would explain the "both directions" part.

    Air India 787 crashes on take off

    Here's another possibility: what if something fell on the switches and flipped them off? (I know they are supposed to lock in place, but again there was a comment in the report that does raise questions on whether the locking worked). I seem to recall a crash of a helicopter a few years ago...

    Air India 787 crashes on take off

    Now, the question becomes: Did the switches get PHYSICALLY turned off, or was there a wiring fault or electronics fault that mis-detected the switch positions? Also interesting that there was a Cat C MEL for "Core Network" active at the time. I wonder what that was about.... They also noted...

    Electric car ship fire.

    I thought I read somewhere that it sank in 16,000 feet of water. If that's the case, that's deeper than the Titanic. I doubt a salvage would be possible.

    Air India 787 crashes on take off

    On Airbus, the thrust levers do not move by order of the computer (not sure on 787 though). On the airbus, the thrust lever setting is more of a "thrust limit" most of the time, when AutoThrust is enabled. (but moving to the full throttle position, called TOGA, will force full throttle...

    Air India 787 crashes on take off

    I'm not familiar with the 787, but with Airbus, those switches are used for the normal startup of the engines and also for the normal shutdown. Think of them as an "engine on-off switch." Internally, those switches send commands to the computer to perform a sequence of events, so it's not just...

    The Airbus design is almost identical to that. But you can't just move those switches. You have to pull up on them to move them.

    Air India 787 crashes on take off

    The counter rollover bugs mentioned just shock me. I work in lifecycle maintenance (bug fixes) for enterprise-level networking hardware and we have had similar bugs in our code, over the years. We used to have our equipment starting acting "strangely" and even crashing if it was not rebooted...

    Air India 787 crashes on take off

    That just seems so unlikely. The gear is located on the front panel, left and above the throttles. Flaps are along side the throttles, to the right. Completely different action needed to operate them. Shaped differently. I'd be shocked if the PNF could get that reversed....

    Air India 787 crashes on take off

    Airbus models are almost the exact same layout.

    Air India 787 crashes on take off

    Assuming the crash didn't move things, that doesn't look like much flaps. Maybe 5 degrees?

    Dominican Republic Nigh Club Roof Collapse

    Not sure how real / accurate this is or the backstory but video is circulating that employees were sweeping up possible falling parts of the roof before the total collapse: https://www.instagram.com/reel/DINRIxsJ2Ns

    Dominican Republic Nigh Club Roof Collapse

    I wonder whether that is a permanent lighting/sound truss or temporary that travels with the performer? About 30 years ago, I was a theatrical/concert electrician and our rigging crews would fly an amazing amount of stuff overhead with medium-to-large traveling productions. In normal concert...

    AA jet and Military helicopter collide over Potomac

    The ATC recording that I heard has the helicopter pilot declaring at least twice that they are using "visual separation." FYI, Scott Manley ran a quick preliminary simulation of the flight along with ATC audio on his secondary channel:

    Boeing again

    If I were those two astronauts, you would NOT be getting me into Starliner for the return trip anymore. Even if Boeing and NASA agreed it was "safe."

    Lithium battery factory fire

    I still have a fixed automatic Halon extinguisher on my boat (in the engine room). Had no problem getting it re-certified a few months ago. They are still pretty common and the certification company said there is no reason to replace it unless it fails the tests.
